Yeah, there is always the feeling when using the blade on the CX, that a slip of the hand could prove to be very nasty. The CX is also pretty slippery with or without sweaty hands.

The cast jaws of the pliers on the CX breaking in the way they have doesn't surprise me either. The crack propagation seems to have originated at the bottom of lower surface cut out (serves nothing to lower the weight of the tool but seems to weaken the tool considerably). I had a similar issue with one of the tips of the long nose pliers on a LM Core (apparently their toughest tool) breaking off.



It was surprisingly easy to snap (break off) the top of 3-4 mm opposing tip using a vice then file up the broken tips to give the modification shown above.
