serration making equipment?

Kit,
The serrations you show are very slick indeed!
Would you mind sending me the pictures of your serration setup...I have a vari-speed bader. Do you think it could be adapted to this machine?...Thanks in advance!:D
 
DSON and All:
Aren't there concerns about the speed that this grinder turns at (4200 RPM grinding speed), and how this hot grinding will affect the steel at the edge of the serrations?

It depends on the stone and the diameter, what size is it. The ones I have used are about 4" maybe 5" which puts it in the range of a lot of bench grinders, so a light hand woukd be required. Some of these are used with mist.
 
I really don't want to extend a discussion about pro's and con's on serrations (Personally don't care for them). But I thought I'd relate this story:

A friend is a professional cowboy (Not a rodeo guy - real cowboy). I asked him to design the ultimate cowboy knife. First they like folders for castrating - OK I don't do folders. So I ask, "what about a fixed blade you can draw in an emergency while roping?"

Serrations - required.

I tried to convince him that a sharp blade will .... "nope, if it's an emergency I want serrations."

Steve,
FWIW, I went thru all that with the Navy EOD guys and got the same answer. My response was to study how and why serrations cut and came up with my design. They loved them and still do. Outward scallops and no sharp points.
IMHO, if a serration won't cut meat, it won't cut much else.
I am more than willing to serrate a sample blade for any of you guys. The final grind after heat treat has to be about .020 thick. It will have a one side final edge since that is the only way serrations cut the best.
No, I'm not in the serrating business but if a customer wants a serrated blade, this is a good one.
:)
 
Kit,

I forgot to mention I really like those serrations of yours. Nice to know the navy guys like something that is also so good looking.

I may have to take you up on that offer.

Thanks,

Steve
 
I've been out of town and just caught up to this thread. Kit made me up a small Model 4 two years ago with about 2/3 of the 3" Stellite blade serrated, and IMHO his serrations are the bomb. I carry the knife just about every day.

The smoothness of the cutting action on stuff like sisal rope, heavy canvas, etc. belies its aggressiveness. I've never used a serrated blade that was this aggressive AND this smooth--no little points to hang in cloth, rope, or cardboard, but all the "chew-em-up" aggressiveness of a little chainsaw. If you can't tell, I'm in love with this serration design--also seems stronger to me than the conventional "concave" scallop design, which leaves the long scallops thinner and more fragile in the edge. The smoothness of cut on meat is also the best I've ever seen from a serrated blade.

Blackie Collins used such "outward scalloped" serrations on his design for the Smith & Wesson First Response rescue knife. While I've never used mine, the scallops are just crazy sharp. They will easily remove extremely thin pads of skin (just the outer couple layers) from a fingertip.

Here's my M4.

Variable serration length helps aggression on a variety of different materials, but tips on the narrow teeth are just as "smooth" cutting as the wide teeth. Result--no snagging or "fits-and-starts":

Will's right,these are great serrations.They are very aggressive and will not snag.I'm not a big fan of serrated knives,but Kit's serrations really work.
