Hi all, I’m going to bring up an old thread on bachi. So I know almost nothing about guitar picks, did a little online reading, and got a used book which I am starting to read. //
Two online sites (one a luthier, the other for guitar instruction) offered some insightful info on flatpicks and tortoiseshell replacements.

High on the list, Red Bear Trading’s picks made of casein. But seems hard to get, very expensive ($27+ each, but slightly cheaper are some made for Strings and Beyond); then some reviewers mentioned crazing or wear so favor other options.
I got Will Hoover’s Picks! book, and I can say, the history of celluloid is fascinating! Civil War guncotton, combustible celluloid and factory fires, variable instability, billiard bombs in saloons, ping pong balls, and a guitar pick that went -whoosh!- in smoke. Just starting to read all about guitar picks and it is fun. (This makes me want to toss a few into a pit fire outside: flame test.)
To test bachi, I got some inexpensive Dunlop. The used, faux bekko bachi I got recently measures about 1.0mm at the thin edge. So I bought thumbpicks with similar thickness, and Dunlop Ultex 1.0mm felt the best of the three I purchased. Faux bekko flexes about 2 inches from the tip then is mostly rigid. Thinking that many start off with wood or plastic bachi, I took a used wood bachi and modified it.
It’s not the prettiest thing I’ve hacked, but it does work better than a hard wood tip. I would say this is like a weekend project, possible to accomplish but does require some effort. Fabrication and machinery would add precision, but this is possible DIY at home. Now if I were to put my business hat on and personal opinion, I would put bachi at the top of needing some change. In that sense, guitar flatpicks will have a thousand more options, partly because of their small size and the guitar market. So the idea of a bachi handle that would accommodate something like guitar picks (swap/replace tips) could be revolutionary.
My try at replacing the two wood tips with flatpick material. I made an error not measuring the second wood dowel, which was thicker so split the oak wood; so to correct and reinforce, I used a Formica patch. This reinforced but took away some flexibility (Formica is flexible, but a layer of contact cement glue and Formica plastic adds thickness). Well, my post is long enough, so here are the photos!

I would guess that a wedge-type bachi handle, flex tips with holes, then setting screws to keep it all in place might work. Change tips by removing screws to release. Quick concept using a laundry clothespin, just to show you what I mean.
