Comments about Dive Rite Dive Rite Z-Knife for vertical Shoulder Mount (AC2059-2):
I used to have a big version of this knife attached to my BC - but it wasn't in a case of any sort and floated around free every once in a while. I like this configuration, but wish the blade was changeable as I know it's going to rust quickly - the other cutter needed a new blade every 2 months during high-use periods. But for the price and the size, it's a dandy little knife!!
