Quick tip: if you don't have a secure way to dispose of the knife break-off, I usually get a piece of tape or something like that to tape around the broken piece when I throw it away. Wrapping a small piece in electrical tape or anything like that will reduce the risk of accidentally cutting something/someone later on.

[@pawemarkowski2768]

Thats what I do too, usually with a piece of masking tape

[@randallreed9048]

Excellent safety tip, especially if kids are around.

[@darikdatta]

Even a piece of paper works well, just fold it around a few times. I also don't like the idea of an exposed sharp blade kicking around in my garbage bag.

[@curt2742]

I usually drop them in an empty bottle before throwing them away. I use tape otherwise.

[@PiriyaSambandaraksa]

One of the most useful techniques I picked up along the way was to hold the knife like a pencil. I teach this to all of my students as it dramatically reduces the chance of slips and slides. When you hold it like that you can't apply too much pressure, so when the blade slips, there won't be too much force behind it as opposed to holding it like in the video. You can also get a cleaner cut by not applying too much pressure, just gently slide the blade a few times and the cut will come out nice and squared. Of course it doesn't work with every application, but for art and architecture, this one little tips has saved so many fingers.

[@notavailable637]

if you hold it like a pencil wouldnt more of your hand be in the direction of the sharp part of the knife? while holding it only at like the top is safer cause if you slip you just drop the knife and not cut yourself?

[@dperreno]

NT Cutter is a Japanese brand that is excellent. It's party trick is that when you get to the end of the blade, just push it all the way out, and when you slide the thumb pusher all the way back it will automatically catch the next blade!

[@FirstLast-ih6ec]

NT Cutter from Japan is actually the company that invented this kind of knives and introduced it to the market in 1959. Great products indeed.

[@runi2453]

Wow!

[@failswithtails]

I bought two NT Cutters because I saw Adam Savage using them. I love the weightiness of the handle.

[@YUGOk45]

Way u break blades makes me crindge.

[@user-uw5jq7ft6v]

I’ve heard these were invented/ inspired by Japanese cobblers after WW2. Resources were real tight so pieces of glass were used to cut leather and when the glass got dull, they would snap off a portion of the shard to get a fresh sharp edge.

[@LRN2DIY]

The origin story shared by OLFA talks about something similar. They don't share the exact details but you're exactly right - it came from re-breaking glass to keep a sharp edge, and the concept of segmented chocolate bars.

[@MottyGlix]

So *that's* why this kind of knife is called a "Japanese knife" in the country I've moved to! Thank you for clearing up a question for me.

[@CarbonTech19]

Used these for decades as a structural aircraft tech and always had the ALWAYS useful, small(9mm) version in my belt holster(along with a 6" scale, scribe, pen and 0.4mm permanent marker). The company supplied both sizes of cutters and an unending supply of blades. Also indispensable in the composite repair shops, where that fresh, sharp 25mm blade came in extremely handy when cutting multiple fibreglass or carbon fibre prepreg layup pieces on the self-healing mats in the cleanroom. Since retired, a 25mm blade lasts FOREVER, mostly opening various Amazon packages, lol.

[@barongerhardt]

As a youth, I worked in warehouses and loved the disposable snap knives. Problems from dirty cardboard, gunky adhesives, and staples would be snapped away. The ones I had could be locked in the fully retracted position. All while being cheap enough to give away. It was part of my EDC for years too. On the occasion of going to security, no need to return the nicer knife to the car or hope it gets past. Just slip into a trashcan.

[@coriscotupi]

I still have an all-metal snap-knife made by Olfa, the original snap-blade manufacturer, that I've been using since the early 70s. My initial use of those devices was not exactly safe, as not knowing any better I'd often stroke the blade toward me instead of away from me. On one of those occasions I managed to cut a slice through my thigh, leaving a large pool of blood on the floor in a matter of seconds. My mom rushed me to the ER, as I kept pressure on the wound. Lessons learned were to never cut toward myself while using force, and never expose more blade segments than necessary for the job. Since then I've had utmost respect for those (as well as all other cutting) tools, with zero accidents since, over the last 5 decades. An I still have, and use regularly, that very same Olfa cutter.

[@bobjones8372]

My lesson was a Buck knife into the thigh cutting hotdog sticks, fixed the almost 2" slice with duct tape though, have a nice scar to remind me.😂

I'm not even joking when I say I strop my snap and box cutters. I know they are cheap. But there is just something about not needing to replace them daily. I pack hundreds of boxes every week.

[@criticalevent]

I run my utility knife blade through a pull through sharpener until it's a hook shaped nub before I'll flip it to the good side :)

[@somon90]

Same, just feels wasteful to snap them off, I use a honing rod before each shift at work and they last until I lose them

[@hampuslagergren4693]

Kinda do the same. Use a Ikea knifesharpener every or every other day to keep it razor sharp. Keeps the effort down when you cut box after box

[@placebomandingo2095]

I use the olfa HD and the blades are stupid expensive but rarely break, so I tune mine up with a little diamond pocket hone. You can also break the yellow plastic off of the HD model and it's very sleek.

[@redwarf8118]

[@Starchild670]

If it doesn't say OLFA, don't bother.

[@BrettWilliamson]

100% agree. I don't do carpentry or any form of building, I work in the print trade. It's OLFA all the way. Quality.

[@tacticalcenter8658]

Can you explain why? I dont care much about brands. I prefer to stand by how it was made. The heat treat, the edge retention from the protocols they used. The quality of the handles etc. Can you quantify it?

[@MarkTrades__]

+1 olfas are the best value. Their full stainless steel model and the models that come with the black coated blades are my favorite. They sell a cheap plastic case you can snap pieces off with and they get automatically collected in the plastic case. When it's full you throw it away

[@MarkTrades__]

​​@@tacticalcenter8658made in Japan. Quality & robust designs. Fully stainless one available is great for industrial applications with solvents/oil. The speed & smoothess of their mechanism that moves the blade is just totally dialed in & is perfect amount of force. Never comes out in your pocket, but effortless to use.

[@Nitrodasnipa]

@@tacticalcenter8658 OLFA knives and blades are made in Japan, and made damn well. I've got a couple that I've used for 3 or 4 years, total metal body, all the paint has been worn off and they're pretty much worn to a polished metal finish. Their replacement blades also come with a little container for the broken off sections which is really nice.

[@krisbacks]

Thanks for the vid, informative for sure. I’m a bit over protective so I appreciated mentioning that big scar. As just a homeowner and crafter that often uses these I want to mention two things for safety. 1. Never leave the blade exposed when not using them. Very easy to close it and reopen. 2. Without having a storage unit I will wrap an inch of tape over the broken off blade and it’s good for the garbage. Overkill? Maybe but I’m old and afraid of the big bad world.

[@CarbonTech19]

An empty beer can works well for projects that generate a lot of blade snaps(put a bend in the can and turf it into the recycling bin or garbage when done), but like you, I'm overly concerned about that tiny sharpish edge cutting through the garbage bag and then severing a limb or my head in a freak accident, lol, so out comes the tape.

[@richarddunstone6093]

The bin men /garbage collectors will appreciate that.

Ounce of prevention pays out big the one time you need it too.

[@nickalfonso8616]

Ive got a smaller Fiskar one and when you run out of blade segments you push it all the way out and it loads a new blade stored behind it. It also came with like 7-8 blades ready to replace when needed and it was like 8.99. Definitely a good buy

I use the original (Olfa) every day, a tad more expensive but honestly couldn't go without. Cuts and strips wires, cuts ropes, strip plastic/cardboard packaging etc, have even sliced up sandwiches at lunchtime, clean excess glue, sharpen pencils etc etc. Has a blunt plate at the rear that works for opening paint cans/unscrew flathead screws/bolts/general undo things that the sharp end doesnt do. And it's high quality, neigh on indestructible. You can get by a whole day never noticing you have one, but you'll instantly recognize when you forgot to bring one.

[@mlukegrady]

Knipex makes a really nice version of this with an extendable spine to stabilize the blade when you extend it out. Also an easy tool free way to snap off blades is to put the blade down on a hard surface at an angle, place your thumb over it and push down, so the blade doesn’t go flying.

I opened it up to find one of these segments placed in a holding slot oriented to cut the thread when activated.

[@JohnUllrey]

Good info, I think I threw away one that probably had a spare blade still inside. I got into building R/C airplanes with Styrofoam few years ago and learned that, at lest for hobby use, you can tune up the razors edge with a standard kitchen knife steel rod to get some more life out of the blade.

In Austria, this is almost the only way knives with interchangeable blades are known. But here they are usually called Stanley knives because they were the largest suppliers and probably the first on the market. If you want to express it without a brand, then these are called carpet knives. Many use a comparable mid-priced version. But most people use the cheap version because in a large pack they usually cost less than replacement blades.

Really awesome Knife and i have it everywhere i go with me.

There are also the much larger variations, almost the size of katanas. It’s said that those were used to slice the nape of a giant’s neck which then causes them to evaporate. Be careful with the steam, it’s a little toasty! What’s great is that replacement blades are always available on your hip, which is really handy. For maximum efficiency, always pair it with a multidirectional transportation hip unit. Much easier for much upward diagonal manoeuvring.

Cutters are more common in Indonesia; in fact, having a pocket knife here is considered highly unusual, along with the downside of having it seized when passing thru a metal detector (which all malls, hotels, and most office towers have by default).

Does't matter if you cut cardboard and drag blade over the concrete because you just snap tip and it's fresh and sharp, plus it's cheap. I got can i drop blade sections into, and when it's 2/3 full, i hammer it closed and drop into scrap steel to make sure it won't cut.

I am using snap blades since I was in high school in the eighties. And I never understood why the notch only was in the first blade. Now I know it is an indicator, not a tool to remove the plastic from wire, and that people only use it for that. Now I understand why it isn't in all pieces 🙂

[@rextransformation7418]

I'm surprised you haven't covered one snap knife in particular which is automatic. Meaning, it has a storage just like the yellow one you've shown, but it's been so cleverly designed that after snapping off all the portions, once you reach the end of the blade, you retract the black scroller (or whatever you wanna call it) and it literally slides in safely a new fresh blade from the storage. I have that one and it's awesome, but it's a Chinese brandless snap knife so I've no names to give. I guess what I've described isn't around as much as I thought.

Great video. I now want the Fiskars, even though I'm not in need of such a knife :) Re: wire stripping, don't do it like that. Any professional electrician will say the same. That puts cuts in the conductor which weakens it, more than you might think. Then as it's bent (e.g. around a screw or inside a wire nut) it's more likely to break at that point. Especially if it's bent back and forth a few times. Novices should use a stripping notch in a pair of pliers.

Had an accident similar to yours while being a kid. Been paying close attention to safety dealing with sharp objects ever since

[@DrBlort]

TIL that mine has the extra blades inside, I had it for years! hahah! Thank you!

[@Denamic]

What I like about my main utility knife is that when you slide the button all the way forward, the blade comes lose, and when you slide it all the way backwards, a new blade is automatically fitted. You can basically reload it without opening up the 'magazine', which holds up to 5 blades. It's really handy.

Fyi, regarding wire stripping, if your blade touches the copper as you spin round, you have just made a fantastic stress riser, and that wire is now mega compromised if it gets wiggled or vibrated. Try stripping two wires, one where you let the blade nick the copper, then one which you didn't, then wiggle the copper back and forth. The nicked wire will snap at the nick in let's say ten wiggles while the one stripped carefully Wil last 50 or more.

These are great for cutting into giant napes.

[@johnnymnemonic69]

Lol yes!

[@AnthorOne]

Thanks man!

[@AlejandroMeri]

4:39 ...That's a stretch... You could use ANY part of the tool to hold that piece of plastic...

I really like my stanley snap knife with the automatic blade magazine, you just pull the blade from the front and you have a fresh blade

[@FireOfJagz]

The best feature of these blades is that they can snap when you don't want them to. I once cut in the tip of my thumb quite deep when the blade snapped. Luckily my nail got the most of the impact, otherwise it would've been a lot worse

[@electrotsmishar]

That notch can be used for etching acrylic sheet as well

[@GYTCommnts]

Great video! I thought for a bit you were going to give some tips on how to reuse/recycle/dispose the little snapped parts, but great insights nevertheless.

[@somon90]

I'm just using these in ways that aren't recommended. I'll remove all locking mechanisms so I can get the whole blade out with the flick of the wrist to get at the plastic wrapping around the pallets at work. I don't generally use the snapping action but rather hone the blade before each shift with a honing rod. I also like snapping the first portion of the blade at a flat angle for a squarer blade.

[@alexhajnal107]

Any suggestions on the best way to dispose of used blades? Not just these but X-acto blades, etc. as well.)

[@jordan38r]

put them in a clearly marked sharps container and then u can take them to metal recycle center, but they may not take it cause those containers are also used for used needles. if u have weekly city recycle service just put the container in the there.

[@joscelkentmanzanero1990]

I use the notch on the blade to score acrylics/plexiglass in a pinch if I don't have a scoring tool.

[@rsporsche]

You can also get versions of these knives where you can load multiple blades and there's a latch to remove a used blade and the sliding lock part automatically picks up a new blade when fully retracted.

[@NegativeROG]

Dude, I've known about these things since grade school, and I'm mid-50's now.

[@LRN2DIY]

They've been around for ages but I was hoping to shed some light on some of their cool features that not everyone knows about and, hopefully, introduce them to anyone who hasn't heard of these before.

[@divinenonbinary]

You really got me with your pliers trick I was like there’s no way this guys making video abt these knives n telling us to use pliers 😅😆

[@FerretPirate]

Love your shirt.
