What are you gents carrying with you to touch up your trad heads in the field? I've got one of the Ace sharpeners, just wondering what everyone else is using.
If I'm backpacking in I usually just use the leather on the underside of my armguard to strop them periodically and keep a DMT folding sharpener in my vehicle.
If you are using Magnus broad heads the Redi edge carbon hand sharpener does a fantastic job. The angle on Magnus heads and the sharpener are identical.
