I recently purchased a new backpack. It has a hip belt that interferes with wearing my Buck 119 knife on my normal belt.

I have seen soldiers with their knives attached to a shoulder strap, pointed down. This seems like a convient way to carry it.

What is the best way to attach the two? Some look like they just use duct tape or something similar. I would prefer something a little cleaner and neater.

Any suggestions?
