Luckily I ordered 2 sets of replacement blades. Installed the first pair and found that it was already cracked. The second set isn't a problem, but doesn't straighten up evenly when clamped like the original. Only one way to tighten, so never misfitted. I can no longer cut the braid because there is a small gap on the knives. Heavy mono, no problem. sorry problem For expensive pliers that are now completely useless to me because the wire cutters don't fit properly
