First Heat trating D2 & Elmax steel

[@adofa8854]

Nice Video Thx🎉! Can you Tell me in what Kind of Aluminium foil you protecting the knives with? And what did u you do after the treat heatment from 1080 degrees? 2x 2hours 200 degrees after that? ❤

Hello. Why people use compressed air for cooling, not the oil?

[@2FRESH-4U]

Air quenching with plates these steels don’t get the oil quenching

[@adityafirdaus3881]

Awesome video, Sir. Thanks for sharing. But may I know is D2 steel can sharpen by sandpaper? I've ever heard that it's hard steel to sharpen.

[@alkiviadis-tsafos]

I don't have try to sharpen any blade with sandpaper but I think all type of steel is possible to sharpen with sandpaper with patience. Thank you.

hello, could you tell me, if I use a gas oven, how long do I need to keep the knife in the oven for tempering

[@polanecdeni]

You can't quench stainless steel in gas oven. They need soaking time(depends on thickness) at steady temperature. U can use oven for tempering tho.

Hello, based on your experience of knives to use in the open air rather a D2 steel or stainless steel as M390? Let me know which one is better in this field according to you, your videos are very beautiful. Hi Michele.

[@alkiviadis-tsafos]

Hi Michele. For the open field like bushcraft etc. i think the better steel is 01 or 1095 (non stainless) Between D2 & M390 I think better is M390 because D2 is dangerous to cracking edge during the chopping and batoning work. For stainless steel I prefer 440C. Is for general cut work with easy re-sharpening.

[@pby7705]

I'm looking for steel on bauschkraft. I had chosen D2. Now I read your post, it is not suitable for chopping and batonig. The second option I have either 440C (N695 or N690) or ELMAX - I require good flexibility, and long-lasting sharpness. Which steel you will be more appropriate ? Thank you very much

[@micheletennis87]

What do you think of the 'M4 Lionsteel in M390?

[@TheOneAndOnlySame]

D2 is perfectly fine for chopping and batoning ...

[@greekveteran2715]

@Therka Marka Not always a trade off. I have ballbearing steel custom knife, that sharpens easily almost like 1095 and holds it's edge longer than Lionsteels M390...

Hi, would you mind explaining the importance of putting the tissue inside the foil wrap please? Thanks, Ben

[@alkiviadis-tsafos]

Once we have to hardening stainless steel must be put the blade inside the foil envelope because we must keep out the oxygen from blade surface. So i put one small piece of paper because when paper is burning the flame ''eats'' the oxygen who there is inside the envelope. (bad English...i'm sorry)

[@oldhairpin]

Alkiviadis Knives Thank you for the reply. And your English is perfectly understandable :-) I like the logic of the paper in the foil

[@bigbob1699]

Please be careful cutting the foil after hardening ! It can be sharp and rip you good! ?What hardness did you get before tempering?

[@alkiviadis-tsafos]

Thank you for your advise. For this time I do not measure the hardmess before tempering.

τι αντιστασεις χρησημοπιοιτε στον φουρνο σας . κανεντε μονο βαφες εαν καπιος σας στηλει το μαχερι του ? ευχαριστω

[@alkiviadis-tsafos]

Τις αντιστάσεις τις έφτιαξα μόνος μου αγοράζοντας ειδικό σύρμα από το κατάστημα ''Κλαπάκης'' στην οδό Αχαρνών 230. Κάνω βαφές μόνο στις δικές μου λάμες.
