My Queen Mountain Man slipjoint cut the knots out of about a half mile of rope so I could splice up the groundlines to my lobster trap trawls. I finally managed to get a decent edge on the D-2 blade and it held it nicely while cutting the 3/8 inch synthetic rope. It doesn't help a knife's edge when the rope has sat on a sandy bottom all winter and the grains get impregnated in the strands. I hadn't carried the knife for a while, preferring a serrated blade for this kind of work, but after coming back onto bladeforums and browsing the traditional forum, I sharpened it up and stuck it in my pocket again.
