    A couple of months ago I had a visit from a local horseman. He was asking if I would be willing to develop a knife to be used primarily for quickly cutting lead ropes, lassos, and similar ropes used to tie or "work" horses and livestock with.

    In this part of the world, whenever somebody has an incident with horses or other livestock, it's commonly referred to as a "wreck".

    Here are some pics of a couple of Prototypes I finished up today:


    "Wreck Knife" Prototype #1: 3" blade, with variable serrations for 2/3 of the blade length. Flat ground with convex edge. On this one I decided to leave the point blunt, which I hope will lessen the chances of cutting up a horse if the need arises to cut a saddle girth (strap).
    I have to give credit to my wife Cindy....she walked into the shop when I was testing both knives, and I made the statement about having to put handles on them tomorrow. She suggested that I cord wrap them....and I really like it.

    "Wreck Knife" Prototype #2: Same blade length (3"), but with a slimmer profile, and sharp point, The biggest difference is the serrations...the are small, with somewhat flatter points, and set up in a 2 small, 1 large configuration.

    I've tested them on nylon and cotton "lead" ropes, and both go through cleanly with tension on the to turn them over to the individual for more testing, and see which he likes best. The toughest part about this type of knife is getting the serrations "right". I spent the better part of a day, trying different combinations and sizes of serrations before I settled on these two.

    On a side note, I stumbled upon a method of etching my name that I really like! Prior to doing any final finishing on the blade, I etched both on the highest setting on my "Personalizer Plus" Holding the etching pad on the stencil for a count of ten, then lifting it for a count of 5. I repeated this for a total of 10 cycles, which "burned" the mark in deeply. I then switched to the "mark" setting on the etcher, and did the same thing for 10 cycles. When I peeled off the stencil, there was a lot of "black" around the mark.....but after a light hand sanding with 600 grit, and a quickly "once over" on a super fine Scotchbrite belt, the marks came out great! Here I've been stumbling around with this etcher for over a year now.....and finally figured out how to make it work the way I want! :)

    Ed, those look great, and I appreciate the thought behind the blunt nose on #1. When you got to cut something fast, you want to only cut what needs cutting, and nothing else. I'm no horseman, but I dive, and if you're tangled, panicky, hogging air, the last thing you want to do is inadvertently cut something important while you're cutting free. And I think Cindy is a genius - the wrap is perfect!

    Your right! Hats off to Cindy.....sometimes we (I) get caught up in a "box", and never even consider other options until somebody brings it to my attention!

    Those look really good Ed and thanks for the etch tip...I am working with a used unit I recently picked up and like a nice deep etch as well.

    Amen to that Steve! If it weren't for those wonderful Ladies, I suspect we'd both be broke and in the poor house! :)

    Great looking and well thought out knives. That blunt tip would sure be handy for a Paramedic also, looks like just the ticket to cut a seat belt of clothing out of the way in a metal "Wreck".

    On the etcher, its kind of funny when "The light goes on" I had the same problems! ;)

    Can you explaine how you did the serated edge?

    God Bless
