I would desperately love to credit the source here--I remember reading this idea in a blog a while back, but am durned if I can find it again. But thank you, nameless artist, if you find this, please step forward and claim the credit!
It's so brilliant--and shame on me for not thinking of it myself, given how indispensible my jeweler's saw has been over the years.
You know how when you are trying to cut paper thin slices of canes,
and you work up a sweat trying to hold that blade absolutely tight?
Well, kiddo, let another tool do the work for you: Take your jeweler's
saw, remove the sawblade, adjust the frame to the size of your
sharpest tissue blade, insert, tension, and away you go!
Really. It does make slicing a whole lot less effort, and much more consistent because your blade won't wobble.
