How to dull a knife blade?

[zach2556]

Now, I know people will read this, think I'm an idiot and not even open it, I have a cheap butterfly knife, and I want to learn to flip it good and I don't want to cut myself, so if anyone knows a best way to get the knife super dull

Put some tape over the blade.

First, assuming your blade isn't sharp on both sides, there's a "safe handle" and a "not safe handle". When holding one of the handles, when you flop it open and then flip it again so the blade touches the hand holding the handle, only one side of the blade will touch your flesh. If that's the sharp side, you could get cut. Holding the *other* handle instead, will insure that only the non-sharp side of the blade can hit the back of your hand.

Second, if you really want to dull it, place it edge first on a sharpening stone and pretend you are trying to (gently) cut through the stone. That should round the edge off pretty good. Saw back and forth until you feel the edge is dull enough for you.

First off, buy a non-cheap balisong or trainer...

The last thing you want is to have a cheapo bali handle break off mid flip and impale something with the now highly mobile blade.

And getting little nicks here and there is part of the game. It's also a good test of your first aid skills.

Run the edge down a concrete brick and tape it up(not too much tape or it won't fit back into the handle).

I know a guy who had a cheapo that was dull as hell. He would throw the bali in the air and catch it however it landed because it wasn't sharp. Sometimes he would catch it by the blade. I say leave it sharp that way your forced to do the manipulations correctly. If you make a mistake you'll get a little cut. Keep the band aids and the neosporin close by.

If your intrested in a trainer this one looks decent.

At the risk of public ridicule...

When I was a mid teenager, I was pretty good with one of these, or so I thought. At my Karate teacher's wedding, which was held at the dojo, a few friends and I wandered to the weapons counter and looked at and touched some of the weapons. I pulled out a "butterfly knife" with a blade a little different than the one I was used to and proceeded to open it at high speed with the standard 3 flip opening.

On flip #1, the slightly curved blade of the knife engaged the first digit of my pinky (on the knife hand) cutting it basically to the bone. I cleaned up the knife and put it back, and tried to control the bleeding on my finger. It took a while to get it under control. Not an awful cut, but not a "nick" either. Deep and severe enough that I still have the scar today. People these days would probably have gotten a stitch or two.

So sharp butterfly knives can be dangerous IMHO. At least to my little finger!

Thanks Roger, I haven't been able to embed videos on here for some reason lately.

Another good trainer is the Typhoon from knifekits.com. It's a little over twice the price as the Bear but you can sharpen the Typhoon later if you chose too.

Yes, Jeff is awesome (cutlerylover) he helped me SO much before I transfered to bladeforums for more advice, hes a heck of a guy

To answer your question, just put some electrical tape over the blade... trainers or purposely dulled knives are sort of pointless unless you're in an area where balisongs are illegal.

Bradley Kimura is only $80ish dollars and comes with a great warranty... first non CCC butterfly knife I've purchased, and I am thoroughly impressed by the quality and warranty support

Painting masking tape might be better because:

• it holds better
• you can fold the tape before the blade and leave a line of folded tape in front of the blade
