Rope Cutting Test Usefulness

[SilverAlert]

Rope cutting using a single knife provides marginal useful data. But performing the same tests on multiple knives using the same technique can lead to some useful comparison data.

Thread 'Ranking of Steels in Categories based on Edge Retention cutting 5/8" rope'

Nov 24, 2010

What I have done is rank the steels in Categories based on edge retention cutting 5/8" manila rope. We are looking for big differences here, not ranking the steels in order such as 1,2,3,4,5. The categories or groups mean that one can expect those steels in that category to have close to the same performance as the other steels in the same category. The categories are ranked in order by edge retention, category 1 will have better performance than category 2 etc.

The Custom Phil Wilson knives in M390 (62) and ELMAX (62) are not added to the data, they wouldn't fit into any of the...

My first thought. There has to be a standard (no possibility with rope test) or at least one other knife (even then,variables that cannot be removed) to yield a relative lesser than or greater than.

Regardless, (knife, sharpening and whatever magic you added) that's a helluva useful knife , standalone, at least to me.

The post I referenced was not mine. That was Ankerson's. He used different methodology than I did and did significantly more work. My posts are buried in this subforum.

Interesting. Although there is the question of consistency in the test medium, you conveyed the general trends. I haven't cut much bamboo, but in my experience it is hard on knife edges.

Who did your rehardening?

In video - I mentioned inconsistency in bundle and stick/cane sizes however treat that as unimportant, just focus on complete the cuts as primary task objective.
I(BluntCut MetalWorks) hardened & rehardened these tested knives except for factory/control 60rc D2. S35VN & D2 could ht 1rc higher where vg-10 max out at 63rc.
