For years I have used microplanes and files instead of rasps. The microplanes are cheap--both in quality and price, but they cut wood like the dickens when used correctly. The problem is they easily cut more than needed. Furthermore the rasps generally available today suck. Yes, they suck the joy out of woodworking because they don't actually do much to the wood. I could not afford product from the likes of Auriou in the past
I suppose a definition of 'elf plane' is in order. The term came about as I was explaining how they work to my kids. I showed them a jack plane and explained that each little piece on the microplane was like a little elf holding one. So, naturally, it was christened the elf plane. Now I have Jack, Block, Smoother, Jointer, and Elf planes.
Getting back on track.
Highland woodworking had a sale on Iwasaki files a while back and I picked up my first two. Though they are billed as files, these things are really rasps. Good rasps.
The rasp fits tight spaces like this far better than the microplane. The rasp also has a true flat surface to reference itself against; the microplane has a slight curve across it's face.
EDIT: I really must have been tired last night as I left off the whole last paragraph somehow.
I am now convinced of the superiority of a quality rasp after my experience with the Iwasaki files. The cut of the wood is more controlled. The durability of the medium and flexibility of the thinner profile enable a wider variety of uses at various stages of a project. I am not getting rid of the elf plane as they are just too darn useful for hogging off wood. Besides, you just never know when you may need some grated cheese or lemon zest while working in the wood shop.
