I prefer titanium, and a blunt tip
Ditto.
I have a mini (2.5") BC knife, and a 5" BFK in tactical holster. Both have:
- titanium blades
- 1" markings/ruler etched on the blade
- blunt tip for prying/screwing (and saves a BC/wet-suit purchase)
- sharp straight edge
- sharp serraded edge
- fishing line notch
- hard plastic sheath (locking of course)
- homemade shock-cord lanyard for wrapping around wrist during use, and for placing over the sheath end for positive retainment (redundant to locking sheath)... the BFK's lanyard is larger (stretchs over the end of a larger sheath) and has a cord stopper on it.
The BFK also has a nice thick 1" knob end to double as a tank knocker.
The BCD mini knife is bright yellow which seems like a good idea considering how small and light it is (easier to see/track while using it with gloves on... not a problem with the larger BFK which is grey/black).
I also carry SS medical shears with a decent sized cable-notch I made using a Dremel and a knife sharpener tool.
If I had to replace the BFK I'd consider SS. I like the idea of a light, rust-proof pry bar, but SS is stronger than Ti for the same volume, especially if prying or scraping at odd angles.
I suppose I could consider a pointed tip if it was a BFK... definitely not with a smaller knife though (since they're more likely to be BC mounted near bladders, hoses... and my torso

).
