I'm trying to get a screwdriver to swap out the strap on my KVF RM055... Want to replace the red with white straps, or maybe red canvas straps. If you've found a tool that works, please PM me the link. The one I got off Aliexpress (surprise surprise) didn't work as it was too small. Need a KVF 4 prong. I tried the TD but they can't get the screwdriver, so I'm stuck. I've already got the strap to swap with (Aliexpress again...) but have no tool to swap it in. Otherwise, I'd have an answer to OP's question. Lol.
