This vid shows a spyderco P-salt with sharp plain egde cutting threw a Leather jacket like a hot spyderco threw butter. enjoy

Didn't know people argued that.

I was always amused by the thought of receiving your first Spyderco in a USPS/UPS box and not being able to open it for lack of a knife. Like locking your keys in the car.

It's a really cool vid but not really a myth. If it was a serrated edge it would be more controversial of a topic but still believable if sharpened properly.

Thanks for sharing!

..but can a serrated edge cut a silk komono? :)

Sounds like something for these guys:

I once stabbed a fully serrated Endura (all zytel) through a Level II kevlar vest front panel. Big woop. I wore a leather welder's glove on the knife hand and had the vest panel clamped in a bench vise.

I hope that wasn't your dress coat. Your mom will be pissed.

I don't know who or why anyone said this is a myth. Leather is made of cows, and it was cut up from the cow to make the jacket. Leather might help save your skin from road rash, but a sharp blade swung with force will glide right through it.

Myth: you can stop after buying only one Spyderco.

For my next video... can a 9mm hollow point get through a leather jacket? Or do you need FMJ?

Not a myth, but not not one either. I think I heard that PEs are supposed to "slide" over some surfaces, while the SEs will dig into it and cut. Maybe this is what the video's focused on? And there's the inverse, that a PE will cut through while material will accumulate in the SE's teeth and stop it from cutting.

Yea I think this is what it is. I think that some people think that a serrated edge would be the best for getting through clothing and things like that because it is so aggressive, and the plain edge won't cut near as well because it is not near as aggressive. Really, the serrated edge might get hung up or caught in the clothing when the plain edge slices clean through. Just my thoughts on the "test" I'll call it.

Typically a jacket is discussed within a self-defense thread (ugh, fun). The belief is that the teeth of a SE knife will provide enough traction to move the jacket from the skin as it's a loose covering. The counter-point with a very sharp PE is that it doesn't have that same friction so penetrates through the layers.

In the situation where you are cutting any static object a SE blade will provide traction to dig and the material will stay put. In this case the blade isn't sliding away when the teeth peaks start the cut and the arcing scallops provide changing edge angles.

I'm a LONG ways from a physicist but that's the logic I think people are referencing. Basically the sharper the blade the less friction it produces in the cutting process, serrations just multiply that process for better or for worse.

That depends on what kind of steel your full metal jacket is made out of. Of course, a jacket made entirely of metal would be very cumbersome. :)

Not saying a well sharpened PE Spyderco won't slice through leather, but are we sure that jacket was leather? To me it looks suspiciously like the hide of one of these critters...

I used the car key to open my first knife. :)

I dont get it? I have been working with leather for some time and been using a plain edge....most leather workers use a plain edge so my logic says yes.

It's a rabid Nauga! Run for your life!

there are many kinds of leather jackets. Try to use jacket of Gestapo or SS officers and you will see high quality.
