Love them i'm a fisherman had my old Klein Pliers for years until some idiot tried to do a float test that idiot being me anyway got my new pliers put some new paracord on the handles put them in my pliers holster and went fishing a couple of days later out to the Santa Barbara Channel Islands to my dismay my new Klein Pliers would only cut my Braided Fishing Line on the bottom 1/3 of the cutting surface the old ones would snip through the braided fishing line along the whole length of the blade so i contacted the seller who by the way was not Klein but a supplier i waited for days but no response so i returned them ordered another exact pair and the new ones cut through the braid along the whole length of the cutting surface like my original ones I know what your thinking Klein Pliers are for electricians True and there are a lot of other pliers that will do anything a Fisherman Needs including cutting Braided Fishing Line and cost less than these Heavy Duty Klein Pliers But every once in a while someone gets a fishing hook in a hand, finger, leg or some other unique place and the barb has to be cut off so the hook can be pulled all the way through so without a doubt these Klein's are the best Possible tool for the job Heavy Duty Klein 8" Diagonal Cutters are the Best even on Hardened Fishing Hooks ... show more

  • D2000-28 are straight
Style: Diagonal Cutting Pliers
D2000-28 are straight. Straight dikes! That's kind of an oxymoron, huh? The Amazon listing is mistaken. It says they are "angled head", they aren't. These ones are straight. If you want the angled head (and who wouldn't), you want D2000-48. Or that other model with the gommy handles.
