A) The knife is surprisingly well made , the blade running on ball bearing . The only issue I had with the knife was when fidgeting the knife . One of the axis lock nuts came lose , and the main blade screw also came lose . Both needed thread lock . Otherwise the knife is tight and straight . The axis lock works like a charm and there is no slop to speak off .
B) The axis lock uses a more conventional spring system . Feels both solid and smooth .
C) Cutting rope , the edge started off really well , but around 100 slices the edge had trouble with the paper . I put the blade to the Wet Stone Grinder after the slice test and the factory edge was some what FUBAR ! ( This seems to be getting to be a knife theme ) . Anyways I was able to coax a 250 fail from the factory edge . But to fair , that factory edge was very poor . And just what the heck is the blade steel ( mystery steel ) . The blade has 20cv printed on it , but the seller claims D2 .
Either way , this was not an expensive knife . The aluminium scales / body of the knife are two parts .. This makes the knife thin and light as well relatively strong . The ground edge has fractures , one which is large enough for my fingernail to pick up . I would grind it out but I would be grinding away a few years of use . The back 1/3 of the blade still has bad ju ju ( grind ) which would take a lot of grinding to remove .
I will re test with the ground edge , but that one large fracture ... Might cause issue with the paper slice .
This is not the first blade I have seen where the edge is fractured and is most likely caused by the heat treat .
