The attached photo shows a set of miniature spoke shaves that I do find useful. They are gripped between the thumb and forefinger- both hands and pushed or pulled. I bought them in 1965'after seeing them used by professional model builders at the University of Michigan''s Naval Architecture Towing Tank. I believe that the set cost less than $5. They are no longer available new but occasionally show up on EBay.
They are available from Lee Valley.... http://www.leevalley...681&cat=1,50230. Now, $36 CDN, though. I have the set and they're very nice. I bought these instead of LV's miniature spoke shave.
