Hi,
I can't see myself attaching an Chris Reeve Project 1 or 2 or an Randall Model 18 to a threaded walking staff to use it for throwing etc.
For me it feels like using a painting from Picasso and glueing it to a piece of plywood and cutting it up to make a jig saw puzzle, one just should not do this.
Carry your CR or Randall knife for "normal" work as it is a very important piece of equipement in any survival situation (the most important perhaps) and carry a Cold Steel Bushman costing only $10-15 for putting on a stick/walkingstaff to use as a spear if you like chasing boar bears etc.
I have made a walking staff from a 1 1/4"-1 1/2" thick Ratan (we call it Rotan in Dutch) stick and sanded the "point" to fit exactly in the inside of my CS Bushman.
The walking staff is about 5' long and when fitted with the Bushman makes for a formidable spear/stabbing instrument.
The first time I sanded the point to fit the inside of the Bushman grip the fit was to good and it took a heavy vise and my full 250 pounds weight and mussle to get it of the staff it was almost a suction fit.
I'll try making a picture of it soon and post it on my photopoint side.
By the way the upper part of the stick has about 100 foot of 2 mm black nylon rope fitted around it to form a nice gripping area.
That rope is ideal for using in a survival situation as a fishing line, building shelter etc.
Still I'd rather go after a boar (or the like) with a single shot 12 (16 or 20) gauge shotgun with slugs or buckshot.
I once (30 years ago) had a wild boar trying to do bad things to me and my father because she thought we wanted to do her babies harm and my fathers 16 gauge Merkel superpose ended the argument when my father pulled both barrels when she bit in the muzzle.
I wouldn't have liked to end that encounter with a spear I'm not in the Rambo league, never was and never will be
.
Cheers,
Bagheera
