So I'm looking to buy a harness knife (I climb cell towers), something that if I get in a bind will be easily deployable, but also has solid retention in the sheath. Dropped too many knives off towers due to weak pocket clips, so I'm looking for something fixed blade, and with a strong Kydex-style sheath. This isn't going to be a dedicated rescue knife, so I'm not interested in those downward curved, all serrated knives. Main purpose will be to cut through nylon webbing/rope in case of sticky situations, but may occasionally be used as a regular knife (cutting tape, boxes, zip ties, etc). Anybody have some good recommendations? Thanks for any help. Also, willing to spend a bit of money, if need be.
