|Think yes, best grip for climbing!!!! but also grip on the saw..... if you want to cut them: put them on your skates, remove the front wheels (to not cut them), like this you will have a god hold on them, use a hand saw (metal, maybe for wood), take care of the rebound for your fingers...
The other solution is to find a huge, steep, rough street and break with them...
: Are these them? And what should I use to trim them?
: Thanks, UR the best!! :-D
