Depends on what you mean by "offset." As shown in the pictures above, the fletching can be adjusted to fit different sized shafts, as with most fletching jigs. However, you can't change the orientation of the fletching to the nock, as you can with the Martin fletching jig by simply turning a dial, or with the Bitz by changing the nock indexers. At least I haven't found out any way to do it, without major surgery on the unit itself.
Another problem I have found with the Bearpaw is that the clamp is fastened to the magnet holder such that there is a big flat piece of plastic right next to the place you put the glue on the fletching, which I find it easy to get glue on. The plastic of the Bearpaw clamp must be different from the Martin plastic. I can flake excess dry glue off the Martin clamp with my thumbnail, but it seems to adhere more strongly to the Bearpaw clamp. Of course, this wouldn't be a problem if I were more careful with the glue!
