I applaud your insiteful and informative videos. I have incorporated your suggested mods to include: 2 zip ties (around knife holder insert, around right column) metal bushings in stone holder, adjustable bolt, nut, magnet, wooden shims under knife supports. I note that with larger and longer knives that under support near the handle distal end, tip and middle decreases flex. If you run the sequence of stones to ceramic and then flip over resetting the under supports and repeating the sequence this makes it more efficient. 2 questions/issues: 1. With cleavers 3-5 inches wide i find limits to adjusting angles greater than 22-23 degrees as the columns are too short. Any suggestions? 2. With most longer blades the angle can vary .75 to 1.5 degrees when sweeping the blade from base to tip. I note that most sharpened blades on the web have a visably wider bevel near their tips. I have a 10" Friedrich herder/solingen blade that measures 20 degrees at the holder and 14.5 at tip. If I sweep the holder area and then reset the tip area to 20 and sweep will this keep bevel more stable? Last question: stroke options are: push, pull, lateral, saw. I watched some videos that reported a push stroke resulted in the sharpest apex. Your thoughts?

Stroke direction matters only for the finishing grits - 400 and higher. As long as it’s roughly perpendicular to the edge and you limit side to side motion to a minimum.

The blade width is less important than the behind the edge thickness (BET). On many large batch production knives the primary bevel is parallel to the apex, so when the belly sweeps up, BET increases causing the wider secondary bevel. Setting the blade to maintain tension angle is discussed in this video.

Great channel! I would like to know how you clamp Spyderco flat grinds. Just went to sharpen my first knife a Spyderco Manix 2 and could not figure out how to get a clamp bit that did not wobble like crazy.

I have owned this sharpener and have had some mixed results. I see now how important it is to clamp tight, clamp so that the deviation in the angle is less to nonexistent. I am curious about why you are so concerned with the jump from 400-600? worksharp has done a lot of research to get the best possible grits to be expedient. I also went on Etsy and purchased a universal stone attachment so I can use all my diamond and natural stones that have different coarseness stones all the way down to 5000 and also using compound paste.

Very well explained! By using your "tricks" to keep angle deviation small, is it also possible to create a more or less even bevel if the spine of a straight back knife is very thick and the secondary bevel curves all the way up to the spine? Hope I explained that well enough... I saw home-sharpened blades that almost widened up to a 1 cm bevel near the tip...

How often are bevel angles perfect (or at least near perfect) from one side of the knife to the other? I’ve found that about half of the knives I check with the sharpie have slightly unequal angles and the sharpie is removed inconsistently from one side to the other. Great series!
@CuttingBoardRx
@CuttingBoardRx 8 ай бұрын
You’re spot on! A typical tolerance for an angle called out on a typical engineering drawing is +/- 3° in automotive, +/- .5° in aerospace, and +/- .2° in precision measurement equipment industries. Here we are, splitting hairs for the noble purpose of slicing cardboard. 🤣

Can you cover sharpening a narrow blade like the benchmade flyway or a fillet knife? Benchmade claims to put a 14 degree angle on some of their blades. The sharpener is marketed to down to 15 degrees with the clamp. With a wide blade, I would think you could get lower angles much easier than with narrow blades where clearances on the clamp would be a problem. If 15 is as close as I can get then that is what it is but I am wondering if there is a trick to maybe get closer to the factory angle. I have not tried the table attachment at all yet.

I would recommend buying a good sharpener BEFORE a Medford knife because there’s a roughly 50/50 chance that you will need to sharpen it before you attempt to cut with it. 🤣 I love the USMC FF looks and mine had a great edge, which could not be said about the Infraction, Slim Middy, and Hunden. The other 2 were Ok.

So based on the your input, it’s not a problem that I would worry about too much. As I showed in the math segment of this video, the difference in the edge width will be very small. That said, you could play with the blade position and orientation: it doesn’t have to be centred or parallel to the jaws of the clamp

@CuttingBoardReviews I'm happy to hear this because I've ran into the same thing while using mine. I can't imagine using the sharpeners with narrower stones because even these want to roll if you're not locking your wrist when pushing or pulling off the tip.

the width of a stone doesn’t matter all that much especially in the belly area because it is contacting the edge at a single point. I’ll address this in another video

I have the same sharpener that you are using in the video. I rarely check the edge with the sharpie as you have demonstrated and I usually start with the lowest grit. My thinking is that I like most of my sharpened angles to be between 15-17 degrees. Most manufacturers seem to be between 18 -22 degrees or even higher. I do however like a mirrored edge. So what you’re saying is by choosing a lower starting grit, it’s harder if not nearly impossible to get a mirrored edge? Is it wrong not to like the normal factory edge? Of course my decision is based a lot on how thick and wide the blade is. I tend to buy knives that would accommodate a lower angle without having a very wide bevel. I really enjoy your videos and your frank truthfulness. I would love to have a real conversation with you sometime. Thanks again.

I start grits all the way down to 100, up to 1400 then final stropping at 1,.5, and 0.1 microns and the mirror edges are beyond easy to achieve.

It’s not really that expensive. How much do you spend on your knives? It works just about on every kind of knife from traditional slip joints, kitchen knives, sporting knives and modern EDC knives. It should last along time and helps me maintain my knives without damaging or lowering their value by poor sharpening skills.
