One my favorite test for my blades is cutting through a plastic bottle bottom. It’s not as easy at it seems as the thicker part (at its center) is surrounded by a ring of softer plastic which can collaps and get crushed before the edge bites and cut through the center.
So of course the sexy Slysz was put into that testing and was able to cross the bottom but it was not better than the Nilakka which was able to do with more ease.
Why ?

After one year of constant use, I have slightly convexed my zero ground Nilakka and for ten months this folder has never warped or chipped its edge. It’s my sharpest knife with my BRKT Canadian Special in CPM3V. Also the thick spin and thick handle help for transmitting strength into push cuts.
So the gorgeous and thin Slysz is not as confortable for push cuts even with its rounded blade spin and concave titanium handle. Also its excellent factory thin edge is no match for the Nilakka’s.
I will do the test again after some gentle convexing of the Slysz Bowie and then we will see if the Nilakka loses his throne.
