I’ve heard some people saying files are for metal and not wood, while seeing many other using files on wood. I know rasps are for shaping, and certainly not finishing, but is there any reason I would want to use a file for wood?

Plus, are there any specialised files that are designed specifically for wood and not metal?

Thank you!

I never use the same file on both metal and wood but yes files made for metal work fine on wood.
This is my go to wood file!

Generally, a fine file loads up too quick to be of use with wood. However, there are always those times you need to improvise….

If nothing else, a file can make an excellent sandpaper holder. . . . .

Iwasaki wood files from Japan. Files made for wood. Work really well.

Surform files are what you need, they do wood and food,
So if you need excuse for buying some just let swimbo know its actually a cheese and vegie slicer shredder too.

A wood file is generally called a rasp.

I use my metal files on wood, not going to hurt them.

If doing fine shaping on wood, I use a file. Better finish than a rasp.

They said above, no harm in using metal files on wood. I just did that this morning. They are a little slow at wood removal but sometimes that’s what’s needed.

I think the gist of multi-purposing hand tools between wood and metal is
the possible cross contamination of metal filings imbedded into the wood.
a good file brush greatly decreases this possibility.
not only just to prevent contamination, but is a good practice to keep your
files in good condition.
there are no written laws of using metal tools on wood. if it works for you,
that’s great. (I am in the multi-purposing camp, myself).

I have a set of Iwasaki wood files, excellent for shaping. I like them better than rasps. I then use files for steel to refine the surface and then sandpaper to prep for finish.

As others have said, metal files work just fine on wood, think of them as an extra fine rasp. I use them all the time when shaping the hand planes I make. Double cut files are a great bridge between rasps and finish work and then progressively through the single cut files to achieve a finish ready surface. Files do need to be brushed out frequently as they clog up quickly in some woods. The harder and drier the wood, the better they work. Something like Osage Orange or super hard exotics file beautifully, while softer woods may only get a few passes between cleanings.

For files specifically for wood, I have some Iwasaki’s and a couple from Corradi. The Iwasaki’s are better going with the grain than the Corradi, IMHO, but vice versa when going cross grain or dealing with random grain, like in highly figured wood or burls.

The Shinto sawtooth rasps are very unique. Made from saw blades, they have a coarse and a fine side, and will not clog up.

An especially unique design, the planer rasp can be used in the middle of a board, unlike other rasps that have inline handles.

I have the 11” rasp and the planer rasp and use them often.

+1 on the Shinto rasps – I have one and they work well and do not clog.

Chiming in on Rich’s suggestion. Great tool!
I use mine to get me 95% of the way there on convex surfaces. Then a finer rasp or even progressively finer grits of sandpaper stuck to a block with carpet tape or Super77.
Here is an assortment and each has its place in my work.

The double knife tip detail file is especially handy too and it has a course cutting end and a fine cutting end. The back is flat and the top is curved. Great tool. I’ve had these for years and I think I got them at Woodcraft.

Small files in multiple shapes designed specifically for wood are called rifflers They are usually sold as sets like these:
