Great!...and thanks!!

I am working on this blade made out of some of the concrete blade steel. It cam out of the quench reasonably straight. The next time I will have some kind of fixture set up to clamp the blade in when I take it out of the oil. What's a good angle do ya think I should shoot for here? The blade is a little under 1/8" and right now its ground about 3/8" up the blade. Once upon a time Joel put a post up that was kind of a cheat sheet for if the blade is x amount thick....and the bevel is y amount tall....then the angle =z I could probably use a re fresher course on

Thanks man....you guys rock. =)

Super interesting.....thanks. Is the chrome going to make it hard or impossible if I try and use it in a sanmai as the outer layers? I guess the 100 dolla question after that is whats it going to etch like...but I can test that easy enough. Is it safe to say that if I oil quench it it wont be as hard....or is that an impossible question to predict.

Thanks for the pic. I will have to see if I can do that. If I was going to keep ol griz I would want a larger work rest like you have. I think if I move my work rest back enough to hang the blade down like that....my 2.5" angle iron wont be super stable on it. Pretty kewl set up for sure. I just use a torpedo level and some notes for what to grind things at.

Soooooo...I just got back from a machine shop that said they would do a hardness test for 10 a pop. He comes back and tells me the sample I heat treated and quenched in water last night tested in the 55-57 rockwell range. I was hoping for more but I guess that isnt terrible. What will I lose tempering ...another couple? I am on the fence here......wondering if that too low. Soooooo ...then he says would ya like to know what it is. Of course I said yes. So he shoots it with his x ray dealio and gets this. Then with a kind of surprised look on his face he says you m

Gosh.....I dont wanna muddy up this guys thread.....but I am all ears if you can explain how ya do that. Either on here or DM. And if not I will survive....I just cant see how. Funny how alot of guys bash a jig.....then I run into guys that will only grind their production blades with a robotic arm. lol I dont care much for the my way or high way attitude.

I do most of my grinding with a jig.....my hi tech jig is an aluminum piece of angle iron and some vice grips. I can freehand ok-ish once I have an established bevel.....but I doubt I will ever be as accurate as my jig. I hear alot of guys bashing on guys using a jig.....I look at it like any other tool. Just because some other guy can take off lug nuts with his teeth doesnt make it a better job than the guy using a wrench. Some things will have to be done freehand....dont get me wrong....like the tip on that tanto. Just my half a cent.

I was told a good machine shop should have hardness testing equipment. I called quite a few yesterday.....one guy said he would test for 10 bucks a shot. Most said no cant help ya. The last guy that told me no I said dont you need to know the hardness of what you are trying to machine? He paused and said.....ya I have a hardness tester...but its so expensive that I dont want to mess with your knives. I think I am gonna cut the machette I drew out last night.....then profile a pairing knife and toss it in the paragon and have him test both. What temp do you guys think w

They are doing some work at the unit next to my work. Long story short I just got these 3 blades in trade for an in and out burger. I am having a good blade day.....right after that my buddy sent me a tracking number for a box full of IPE he had left off a deck he did last year. I am kind of surprised I never see that on blades.....I am guessing its because its a little plane jane. If its durable enough for an out door deck I think it would be great on kitchen knives and filet blades. Any way are these worthy? If so should I try and grind and not get em hot. Or are the

What ya going to quench it in? 15n20 is typically done in regular oil where as 1095 likes something a little faster. I had partial success with canola but I am pretty sure it wasnt optimal.

For some reason I can see any of the pics.....maybe its my security settings here at work.

The title is a little mis leading....I orig. ground and heat treated this blade 2 or 3 years ago. It was my fav chopper until my kid tried to cut screws hidden some chair legs. Sooooo the other day I reground and put a new handle on it. The cutting edge lost 3/8" or so and I THINK there are some spots near the edge that are real close. I can put up a pic after the first etch if ya guys want. It appears to me the last inch or so didnt get hard. Thats not a huge surprise I can only heat treat about 12-13" of blade...and when I pulled this one out of the brine it looked l

Its a beauty......

That I can do....thanks.
