In reply to Bottom Clinger:
Excellent, what size is the hex hole?
Can you tighten an M10 bolt (17 spanner) or an M12 bolt (19 spanner) with it. Looks like a krab can clip through it and could hang on the back of a harness for sport routes. Would be perfect
I already have carabiners with a built in folding knife, which is obviously essential in every quickdraw. You can't be too careful! But they're only for trad mountain routes not sport so I need something for sport climbing. Your multi axe could be the very thing I'm after!
The ones for trad and mountain routes... "Multifunctional Carabiner Tool with Knife Screwdriver Bottle Opener for Mountain" ebay.co.uk/itm/296081090170
