I work in the field as a telephone technician and climb poles for a living. I absolutely would not recommend these unless you have experience with them and do not intend to climb the same tree many times. I definately would not recommend them for hunting where you would stand on them for any length of time. Not only are they hard on your knees but your back as well AND, standing on gafts for a length of time makes your feet go numb even with the best climbing boots.

I think they'd be alright for triming and then hanging a stand with a ladder system or climbing sticks or steps but again they will tear up a tree.

I don't know what your intent is with these but be careful, keep your knees and midsection away from the tree/pole when you climb keep the gafts in the tree at the angle specified. Again, I recommend a climbing stand, ladder sticks or even screw in steps before I would ever recommend the use of gafts....I climb poles for a living and wouldn't use these myself.[&:]
