Looking to buy a cheap set of kitchen knives & dull/round them for more realistic training. Has anyone out there tried this? And how did you do it?
Thanks.
 
It's my understanding that its not enough to just dull a knife to make it a trainer. After all a dull knife can still cut. To be safe you must actually grind the edge off past the bevel and replace it with a rounded edge. Don Rearic had an illustrated explanation of the process but I can't remember whether it was posted here, his website, or at selfdefenseforums.com Good luck.

Best regards,

Rubber trainers from Cold Steel only cost about 5 bucks...
One would be an idiot to use any real knives as trainers, ground down or not... a million things can go wrong...
 
Hello Everyone,

I have several folders that I have ground down, rounded off and removed all burrs from, that I have used in training. Be very, very careful when using this type of trainer in practice!! Since it is thin and very strong, a solid hit will penetrate you!! I have stuck several rounded and dulled blades into a "scarecrow type" dummy with various clothing on, just to prove it can happen!

Try and stick to the wider aluminum trainers as it is much more difficult to penetrate your partner with them.

Safety Note:
At the end of every training session inspect your trainers for any burrs, and immediately sand them off. The slight burr will rip up your partner very quickly!

Even sparring with aluminum trainers is a bad idea.

Self-defense tools like koppo sticks and ComTech stingers are based on the premise that lots of force concentrated on a small surface = devastating impact. A misjudged jab with a thick aluminum trainer can fracture bone. If the edge/point is thinner than that, you'll break skin through sheer force of impact.

Be safe and only do free sparring with rubber knives or foam sticks. The glinty, cool-looking training knives are good for flow drills, quick-draws and maybe some structured sparring when you're at a decent skill level.
 
hmmm. I use alum. trainers and have never had a prob.

I also bought a bunch of Cold Steel folders 2nds at a Gun show they were at for a few bucks a piece and ground the edge off. Work great
 
I've taken (and given) a few hard pokes with metal/wood trainers. They can hurt like heck and I could see a full-on thrust to the ribs might crack something. For anything more than half-speed drills I like to go to some type of soft trainer.
Stay Safe,

I have found that getting some of the CS trainers, drilling out the handle and weighting them down a bit works very well. That way there is little chance of stabbing your partner while having a more realistic feel to the knife. Balacing the blade and handle will be tricky. Really just what feels good to you IMO. Now whether you like the feel of the 3 CS knives is something I really can't help to much with.

If you're good with a knife(lol, like any of us are) you can remove some of the plastic to give a more standard just staright oval handle and the wrap it with anything that feels good to you. The the only thing left is the blade shape you like. That's easy enough to carve to just about whatever you want. And at $5 a piece trail and error isn't a big deal.
 
I use predominately Gunting, Endura and Delica trainers from Spyderco; these are great pieces of kit. I would humbly suggest wearing eye protection while training as we can take a thrust to the body but an accidental poke in the eye and you’re in deep kaka

Play safe
