Making a sharp-edged razor file for binding channels

Bad news: the binding on this old Gibson is crumbling to bits.
Worse news:that binding is the only thing holding the body together!
Dan Erlewine's plan is to replace the binding bit-by-bit, so the top doesn't fall off.

By grinding a new edge on a razor file, he creates a tool for cutting crisp square binding channels without a router.

Super sharp and super efficient!
Imagine putting hundreds of little razor-sharp planes to work while you're shaping an instrument neck.

They're the sharpest fine-cut woodworking files we've ever used. They cut quickly and aggressively, but leave the wood surprisingly smooth. You'll discover they're real time-savers for shaping solidbodies, custom jigs and clamping cauls, too.

A new manufacturing process is the key to Razor File efficiency. Rows of semi-circular plane-like teeth are chemically etched to extreme sharpness, and diagonal grooves are milled at strategic intervals to minimize clogging. Available flat or curved, each steel Razor File has "safe" smooth sides (the flat file cuts on both faces). Early samples of these files were quickly snapped up by our R&D guys for testing in their own shops, and they immediately loved them.

Large files have a 7" x 3/4" (179.80mm x 19.05mm) cutting surface. Overall length including the tapered tang is 9-5/8" (244.48mm). The 3-5/8" (92.07mm) easy-grip contoured handle allows safe, comfortable use. Threads inside the handle grip the file tang securely.

Small files are for more detailed shaping work: tight contours, corners and smaller surfaces. Each file has a 3-7/8" x 3/8" (98.43mm x 9.52mm) cutting surface, 7-7/8" (200.02mm) overall length, and the handle is rubber-coated for comfort.

Instant winner

I bought the large flat and small curved and plan to buy their counterparts soon. They took a little getting used to, they cut a lot differently than a regular file. About 15 minutes on a scrap of maple and I had the hang of it. Quick cutting, and a nice smooth surface, great product, I know these are going to be the most useful tools in my file/rasp arsenal!

I like These!

The first time I used these razor files I wasn't sure I'd like them. To me they had such a unique feel when cutting. Didn't take long to get the hang of them, though (like, a few minutes), and now they're on my everyday go-to tool rack, along with my Dragon rasp. I like 'em.

They work great for me. They are sharp I use the little ones for carving rosewood.

Here's my input on both the Razor file and Dragon Hand Rasps: Recommended!

Love these files!

These are great - much more precision compared to rasps and you can be as aggressive or as gentle as you like. Since I got these my rasps are pretty much retired!

They're good but different

These do not work like regular files and they take some getting used to. They are almost more like planes--they're sensitive to grain direction. Yet with care and practice they can quickly produce extrordinarily smooth surfaces. Be careful not to cut your fingers.

Only the one gripe!!

That is that I hadn't purchased these years ago. Amazing files, just watch your skin :)

The files seem to cut ok. It's the clogging of the teeth that seem to be a problem. Keep a wire brush handy to keep the teeth clean.

Razor file revelation!

Without a doubt, these are the best shaping files I have ever used. Recently, I had to replace a ebony saddle on a Loar spec Gibson F5 mandolin. I was able to rough in the blank and shape it to match the original saddle in half the time previously using standard files and rasps. Also, these files don't leave the "chatter marks" making final sanding/shaping a breeze. I also plan to get the smaller size versions on my next order.
