Thin m390 cardboard cutting test

#1

Post by eloreno »

Hey guys,

I reground my m390 mule with a VERY thin full height convex, to see what it could do. Then I started cutting cardboard. Almost 40 minutes later I had quite the pile of cardboard. I was very impressed with the properties of m390 when ground thin. It can handle it.

Don't worry, the video isn't 40 minutes long. I sped it up.

I figured M390 was kind of like that :D Keeps a sharp edge for a long time :) I won't be worried about mine even though I took the edge down a little from stock.

Impressive pile of cardboard, time to start a bonfire :)

That must have been a workout :eek:

It was indeed a work out!

I didn't expect to cut it all, but the thing just kept cutting and cutting!

That's an awesome video and more impressiive blade. I wouldn't have said
that you sped it up, just let people think that you cut that fast and that you
can speak a second language in Alien. Nice work eloreno.

The blade is indeed much more impressive than the video!
Thanks very much BAL.

How about some macro shots of the edge after all that cutting? Lots of the recent steels CAN do that much cutting, what i'm interested in is how much chipping comes as a result.

Understood. If you made it till the end, you would have seen me run it over a extra fine dmt benchstone twice per side.

I did the fingernail test before the sharpening, and could feel no chips. I can usually feel even very small chips with this method.

I have not touched the knife since. I just shot a video of extreme close up on the edge. I will put it in this post when it finishes uploading.

I have done similar tests with a reground cts-20cp, and it did have a slight issue with micro chipping. I will re-do the 20cp test in the future, and put it all on camera.
Also, I learned a lot shooting the video I shot yesterday. I hope to improve a couple things.

I appreciate any constructive criticism.
I figured you guys would get a kick out of it.

The macro vid of the edge will be here: http://youtu.be/kp1t1AG5nGg

With m390, its rare to get chips even cutting aluminium and tin (yes I have cut some real crap with my m390 para)
