I have been toying with buying some rasps for years now to add to my carving tools.
Liogier is one of the French manufacturers that makes hand cut files. This guy does a good job of the range and how to use these rasps in shaping wood.
But check out this artist and how he uses them to carve a snail neat work.
If anyone is interested in these Rasps the best place that i have found to get them is direct from the factory store online shipping to North America is only $12 flat rate regardless of number of tools.
Here is a link to the store and some deals works out about $200 less for a set than buying them via a distributor in North America.
