Thanks.

Tom, Are the emersons depicted are now a conventional V grind correct rather than that offset stock one?
 
Very nice work.
I see a Pacific Salt, how was H1 to work with?
There was some talk of full flat on H1 being difficult from the factory.
 
Tom,

Amazing precision work! I have a question, how do you preserve the heat treatment?
Of course if it's a secret, it has to be kept secret.

Correct, they are all now a conventional grind. Sharpened on both sides.

The H1 was not a problem to work with. The ZDP-189 is MUCH more difficult to grind!!

No secret. I use fresh belts and slow speed. I also hold the blade in my bare hands so I can feel the heat building up. It becomes uncomfortable for me way before it would affect the temper. Lots of dunks in the water bucket.

Thanks everyone!

Thanks for posting these examples Tom. Outstanding!

Have you ever done a Spyderco Kiwi re-grind? It's a pretty small blade to start with. Would this be a good candidate for your work?

Thanks.
 
Excellent work, Mr. Krein. I particularly like how you "fixed" the Emersons. I will probably contact you in the future for similar work.

I have not done a Kiwi, but it is not a heavy duty cutter so I would think it would benifit if it is over .020" or more. I don't think it would be a problem!

Just let me know....

Thanks everyone!

Cool. E-mail sent for quote and a few other things.

I've seen in the pass around thread, or maybe somewhere else, that a flat thin regrind, is good for 80 - 90% of the cutting tasks a folding knife would normally be used for.

What sort of tasks wouldn't a flat thinly reground knife be good for?

Probably nothing I would use a Kiwi for anyways.

So many things to spend money on when I hang around this forum!
 
Nice looking work, Tom. Can you tell us a little more about the regrind on the Chinook? What exactly did you do to it, and what benefit is derived from the regrind?

Thanks.
 
My flat ground ZDP Endura regrind has been used for all sorts of EDC tasks. I'd avoid metals much thicker than speaker wires or CAT 5 cable unless you have good skill at cutting them (I don't), but otherwise I can't really think of much it can't do. If you want to really beat on it Tom can always leave the edge a bit thicker, but all of my regrinds are .010" or less and I really like the cutting ability, and haven't had any durability issues as of yet. I think Yablanowitz uses his flat ground ZDP Endura with a .010" edge real hard doing construction and hasn't had any issues at all with durability.

As for the pics in this thread, I am drooling. That Chinook is great, and I am starting to really want an Emerson again after having my CQC-7 stolen yeas ago. Most Emersons feel great in my hands, I just can't stand the thick grinds. Now we have Tom to cure that problem. I will definately be getting one of Tom's Ultimate Capers before an Emerson though, but now I have a Emerson (like a CQC-8 or 12) back on my wish list.

I personally think it is good for about 95% or more of daily cutting chores. It is not going to be good for prying...

I will try and get to your email this afternoon. Basically I charge $35.00/each for regrinds less than 4"....

To start with the Chinook has a hollow Saber grind. It only goes about 1/3 of the way up the blade. It is also very thick behind the edge. Mine is in the .035-.040" range. These two combine to give so-so cutting, a very "wedgy" edge!

The tip is also swept up slightly. This in my opinion makes it more difficult to use for edc work. I like a point that is more in line with the blade.

I dropped the tip about 3/16", took the top of the swedge back to increase the radius (I felt it was a bit tight), flat ground the blade 3/4 of the way up and left it .010" at the edge. I also thinned the swedge down and made the tip sharpenable for about 3/8".

To me this is a much better knife. I REALLY like the way this one turned out! It should be plenty strong and is now a cutting S.O.B.!!

Very cool. I wish I had something to regrind.:( Have you ever done a Sebbie and if so do you have a pic of how it turned out?

thanks,

Oil, one of my sebbies will be with Tom soon. I think it will turn out great.
