I have both sizes of the spearpoint, and have reversed the thumbstuds on both. Once I removed them, I countersunk the holes slightly with a diamond rod before reassembly; don't go overboard on this or the bolt will slide in too far.
I've also removed the clips on both (replaced the screws), and used a black dogtag chain as a lanyard on the mini. That way I can loop it through the belt, and get it with one good pull.
The mini has become the main EDC. The full size travels in a horizontal leather sheath I put together one evening.
I have no problems with the liner-locks as there is no handle cut-out (as on other "right-handed" knives)which might allow slippage during a strong grip.
