Marking knives are pretty invaluable in the shop, but there isn’t much to them really. Given that, I really like this well made production. There’s nothing at all ground breaking here obviously, but it’s a good example of making that made me happy.

Well, the video production quality was satisfyingly good, and the accompanying soundtrack was therapeutic.

I'm sure that it's going to do just fine as a marking knife, but that heat treatment of HSS was kind of painful to watch. My suggestion for his next project would be to use a piece of steel cable to make a "damascus" marking knife. He's already done most of the work, and could skip the plastidip step.

Forged in Fire! Ryan, what type of camera was this filmed with? I like the quality.

That was a cool video.....I have a cigar box full of old drill bits. Hmmm...... I might have to give that a try this winter. Thanks Ryan.

So I know I'm a newbie at heat treating, but what was he using the toaster oven for? I thought since he already heated the bit up with MAP gas, that it was heat treated.

Shades of Mr Chickadee videos.

All the information you need, none of the ****** music or hackneyed explanations.

Cool video. The one thing I hate about youtube is, the second some people get in front of a camera they become worse than late night infomercial host's, completely tossing out all if any educational value. This was great, short and to the point....get it? point :lol_hitti

Y'all would cry if you saw me make a knife. I use old vanadium wrenches for knives and 3lb hammers for axes. They're garage sale finds and usually black oxide, broken, or abused. But some guys get weirdly emotional when they first hear about my hobby.

HSS and anything with a bunch of moly in it is pretty low on my list of candidates.

That was great. Makes me think I may be able to do it with out killing myself.

Correct, also called drawing, but not to be confused with cold-drawn steel, which is a different process. This phase of heat treatment restores toughness, as quenched steel can be quite brittle.

Nice to see that you don't need a whole forge setup for such a small project, although it would probably help.

That was enjoyable production.

And I have a non-reduced shank bit to spare.

I personally took great value in the complete lack of a soundtrack. Not even background noise.
Simple project, simple production.
Well done sir!

Wrong End.....the back ends of the drills have a mild steel slug friction welded to them so that they are held in drill chucks a little easier....so that it bites down into it and also so they are not as brittle as the business end. I don't know that will hold and edge at all or that your heat treating did anything to the steel at that end....oops!!
