Making a file handle

I was using the chainsaw to rip wood from someone's apple tree (cutting it into short planks), when sparks started shooting out. I thought the wood must be hard, but later discovered I had cut through a nail three times. Needless to say the blade is sad now, so I went to buy a file, but first I had a hunt around my files (file files) to see if I had a nice one. I have two, one is nearly worn smooth, the other is a little rusty but so sharp it seems like it has never been used - and has no handle (I don't remember where these came from; a garage sale or someone's discards). So I thought about making a handle, maybe out of apple wood (although I have lots of hickory, and I just sharpened up my new (antique) draw knife today). If you give a mouse a cookie.... Anyway, while hunting through the files, I came across a triangle file that I have had since I was a teenager.
I used to make stuff at Grandma's house (pre-teen) with her rasp and vice. Later when she moved out of her own home (and we moved to Auckland), the rasp and vice came to our house. So I had made a handle for this file of mine. The handle cracked when I first put it on (no ferrule) but it is still tight and going strong. I must have made it out of a piece of one inch pine that was lying around. It is pretty greasy now though. So now I have to get busy and make a handle for the chain saw file.
