If you read my post on this subject, you may remember I wondered out loud if the "new" harder blade was better at edge holding than the "older" HT.
Well I did my own heat treat, rather than send it in to a HT provider. I just didn't want to part with beloved Micarta Insingo for a month or more. I was pretty sure I could do it because I've done hundreds of blades of my own. :)There was a bit of pause of course, this is a Sebenza after all.

It's been carried and used for more than a couple of weeks now. I used it as I always do and can say for sure, I like the edge holding better, and have to use the Sharpmaker less. The difference is not dramatic, but I would do it again.

I put a satin hand sand finish on the blade. :thumbup:I got to get another one of these Insingos, CF perhaps.


See the color on the jimping.

 
It looks nice, you are a brave man! What is the shapmaker test? So are you going to run a controlled test to put numbers to the improvement?

How often do you sharpen a knife? I ask because you say you did this one just a couple of weeks ago and can already tell you are using a Sharpmaker less. Not being a smark@$$, that's a legit question.
 
What was your heat treatment protocols out of curiosity?

Aim for secondary hardening?

How did you find the annealing of S35VN?
 
Thanks!
I posted this to acknowledge the move CRK made in increasing the hardness of their blades. Good move!

I usually use the Sharpmaker once a week, with stropping to keep it up now and then, now it's been over two weeks with no need for the Sharpmaker. Not scientific, but good for me.
 
A little confused... Are you comparing the mid-2013 to present day supposed harder heat treat to blades manufactured before that date, or are you heat treating your own blade and comparing that to CRK's heat treat?

Sorry, I find this confusing also.

I thought the same. You posted about this...why not just share when people have questions?
 
I agree, I've found the same to be true. Much less sharpening, seems to keep that working edge for a long time.

Went from 57.5 to 59.5 on the blade I've used the last couple years. Would be nice to know your before and after, oh well.
