The reason to cut the toothbrush handle is to reduce its length not its mass. It fits in a much smaller stuff sack when it's 10cm long than when it's full length. Since that stuff sack contains other things of approximately that length or shorter (in my case, stuff like: nail clippers, travel sized toothpaste, floss, extra lighter, a pair of corded earplugs, headlamp, possibly a spoon [0]) it gets awkward to have one pokey-outy thing when you're shoving it in amongst the other gear in your pack. [0] Yeah, yeah, I know: there's earwax on my spoon and toothbrush. That's never felt that important five days removed from a shower :-)
