that I can send some knife blade blanks to have the edges ground?
Here's the deal. I bought 3 Camillus USMC knife blades from an Ebay vendor. Thought I was getting finished blades. Got one finished blade and 2 un-ground "blanks". My mistake, didn't look at the pics close enough. Saw the one finished blade and assumed all were finished.
Had them checked by an area knifemaker, who said all 3 have been tempered. And that the 2 un-ground will be a booger to grind. Offered to pay him to do it, but he declined. Said he grinds his BEFORE heat treat.
I'd really prefer my practice grinding to be on something I wouldn't mind screwing up. So I'm looking to find someone who will grind them for me. Of course I'm willing to pay, if cost is afforable.
Any suggestions?
 
You have a couple of choices.
Find out what kind of steel they are, aneal them, grind them and have them reheat treated.

Use a variable speed grinder and regrind the blade carefully with a lot of water.

Get real good with some files :)
 
Do you know what the steel is? do you know the tempering temperature used? This is important because it will determine how difficult it will be to grind and how hot the maker can get it without running the temper.
 
do you mean entirely unground, as in steel silhouttes, or are they just lacking an edge bevel?

it seems to me as though camillus wouldn't heat treat before primary grinding, unless they just tossed everything they had left in the building into the kiln before shutting the doors??

grinding primary bevels into hardened steel would not be fun :thumbdn:

Not a big deal on an industrial wet grinder, and less risk of warping and no post HT finishing necessary. I don't know how they normally do it, but I wouldn't be surprised if they ground their bevels in hard steel. And it isn't like the steel was that hard.:rolleyes:
 
All production knives I know of are ground post heat treat. As Nathan mentioned the industrial machines they use flood the blade with coolant or water as the bevels are ground. I would think you could get someone to grind them for you if they were annealed. Of course knowing the steel type will be a big step in reheat treating it.

Yes, steel silhouttes. Stamped out, blade shaped blanks. How do you anneal?
 
I can grind them for you. I heat treat before grinding the bevels on all my daggers and small knives. It just takes sharp belts, bare handed and cool the blade more often. Email me if you like.
 
Thanks Bruce. Email sent.
BTW: According to a website I found on Ka Bar USMC knives, the steel is: High Carbon 1095, tempered to 56-58. I'm sure that means more to you than it does to me.
Altho these are Camillus blades, it is my understanding that Camillus was the original (1st) maker of the USMC knife. And that in fact, Ka Bar was a secondary maker after Camillus was overwhelmed by the quanity of Govt. contract.
All USMC knives were made to the specs the Govt. approved on the Camillus knives, so I would assume these blades were made to those specs. Unless they are rejects.

Just got the blades back from Bruce. He did an EXCELLENT job of grinding the blanks! And I am delighted w/them. Just wanted to post a public THANK YOU VERY MUCH to Bruce!
