The final number is 300 for the LJ.

When I evaluated the edge, I used the area closer to the tip. As the heel area becomes gradually more blunt, the tip area has to assume more workload. I chose a test media I feel like highlights advantages for serrations ...

Im taking my time with testing this edge on the leafjumper. So far 180 units of work, and the vg10 is still passing. I forecast failure around 260/270.

I appreciate the opportunity to purchase these test mules, and have my input heard. Explaining to us the VOP- voice of the process is uncommon in many industries. The transparency, integrity, and the courage to pave new trails are what make spyderco 1 of a kind.

I did a quick sharpening video on my serrated LJ vg10 a few days ago. Im occupied with another project so it will be some time b4 this gets cut tested.

In terms of sharpening, I use a fine india 400 to start. I use 3 different angled strokes to make sure ...

Finished up testing this morning. The k390 cut alot, the plain edge i believe did only 44- this is a 922.7% increase over that.

After 3 trial tests im satisfied with this approach for teeth testing. I believe the testing we have always seen caters to plain ...

The serrated k390 has surpassed vg 10 in my testing. At 260 it is still passing with flying colors.

Im testing serrated k390 today. The model is a police 4 which reaches the next tier of my testing based on cutting edge length. To create an even playing field, I attached a medium binder clip to reduce edge length. Comparison picture against the leaf jumper ...

I can only test finished products with a standardized test. Variation within the way serrations are produced are beyond my control. With several samples tested i think I am representing a fuller picture.

Here are the options I have available to put thru testing in terms of serrations. H1, 8cr, vg10, and k390. H1 is now H2, however if Sal wants me to test H1 I can most certainly do that. The police will need to be binder clipped to stand on equal footing with ...

One of the hardest things on cutting utensils I have had to cut is this Kevlar woven roven that you glass in areas.
I was using it in the Transom of boats to better buildup the area where the engine is bolted to the boat. That stuff is really thick and hard to cut.

Funny thing is the first ...

I sharpened up my serrated leafjumper this morning. However I did 2 tests with my plain edge k390 version. The edge im assuming was a 1k edge did a horrible job. After 10 slices on sanding roll and 10 on the polypropylene rope the edge according to my ...

Some pictures from yesterday's testing.

The serrated vg10 leaf jumper showcased a 30% increase in edge retention today reaching a score of 252.

When I do my sanding roll cutting tests, I envision a warehouse environment with the vast majority of edge wear from corrugated waste products. This newer testing seems to make serrations shine ...

Factory edge did 194 units of work. I want to run another edge to verify that the method i used to evaluate the edge can be repeated.

Im still dialing down specific criteria for the serration testing. Didn't make the progress I'd hope for today, but its a WIP- work in progress

Here's the difference between 1/4 and the 3/8 sized polypropylene rope im using now. Finalizing when the serrated ...

Im content with xhp/rex45/ magnacut on my chiefs already. So im gonna vote pops pro cut with the wave feature cutout.

I have previously done testing on a 15V pm2 along with a crucarta pm2. The lightweight manix was available and I decided to take a different approach because these steels were already tested in fact multiple times just not all listed here. 15V has better wear resistance over cruwear- nobody here is ...

Yesterday I did an experiment with some rope cutting. I used 1/4 inch twisted sisal rope and polypropylene rope on a 400 grit magnamax mule. The intended purpose was to identify where the edge was degrading the most. Since the sisal is synonymous with Pete ...

Before I start testing my serrated LJ, I need to test a few things first in case adjustments need to be made. First I dont have established criteria on when to stop. The edge on this endela has been used quite a bit, and I can reach test failure quick. For ...
