About This Item

It's the best scraper we've ever used!
Revolutionary tools, unsurpassed for smoothing wood surfaces, arched instrument tops, bindings and more.

For an ultra-smooth wood surface, nothing beats a good sharp scraper. Veteran luthier Al Carruth has given the simple scraper a revolutionary makeover, with practical improvements for stringed instrument work: the original Ultimate Scraper. We added a second mini version that's popular for working in tighter areas.

Go for the rectangle/concave scraper when you need to keep a good, tight, square corner in binding channels and neck pockets. Also great for smoothing bindings and many steps of making a new neck. Thanks to renowned bass luthier Michael Tobias for suggesting this new shape!

  • Refined shapes are superior for arched tops and flat or curved surfaces.
  • 1/8" thickness adds stiffness and greatly reduces chatter.
  • Two working edges for scraping with both pull and push strokes.
  • Durable tempered steel edges, for smoothing harder woods.

At 1/8" thick, Ultimate scrapers are much beefier than standard scraper blades. Two cutting edges let the tool work in both directions, without flexing and with less chattering. That saves a lot of time and effort! The tempered tool steel holds a more durable edge, too. The shapes are specially refined for hand-contouring and graduating arched instrument tops and backs, as well as smoothing bindings and flat surfaces.

Dimensions
#0631 Original: 3-3/4" x 1-11/16" (95.25mm x 42.86mm)
#0632 Mini: 2-1/2" x 1-1/2" (63mm x 38mm)
#0623 Rectangle/Concave: 3-7/16" x 1-13/16" (87.31mm x 46.04mm); three straight edges plus 20"-radius concave edge

From luthier Al Carruth:
"In Il Segreti di Stradivari, violin maker Simone Sacconi wrote 'scrapers were made from blades of sabers. Since they were of very hard steel one could not turn the edge and therefore they were used like a knife.' When I began working with violin maker Carleen Hutchins she used such a scraper. This is, in my estimation, the best possible scraper for builders of arched instruments.

"It works on the same principle as scraping with a broken piece of glass; a common technique among carpenters. A very hard material can take an exceedingly keen edge and when it is perpendicular, as it is in broken glass, it can last for a long time even if the material is brittle. This tool has the advantage over glass of having a shape that is well defined and re-sharpenable."

How Al sharpens his scraper:
Sharpen the Carruth Ultimate Scraper on a grinding wheel"I find it easiest to hollow grind the edge perpendicular to the centerline of the scraper. Simply set the tool rest on your grinder perpendicular to the wheel and grind all around. Use as fine a wheel as possible and don't apply too much pressure. If desired, the edge can be further dressed on a fine stone with or without a guide block.

"In use, this scraper will give an extremely smooth cut even on soft or highly figured wood. It has little tendency to chatter due to its weight and does not heat up. It is much easier on the thumbs than a "normal" scraper as it is not "sprung" in use. To re-sharpen simply lap the surface on a fine stone and re-grind the edge."

Watch the video! Al Carruth shows how to use and sharpen the Ultimate Scraper. Watching Al, you'll see how easy this is.

Must have tool

Power to remove even rock hard glue while not digging into even soft flat mahogany. The thin card scrapers are great for curved necks, etc. but this one beats them for flat of some concave areas. Enjoy!

Amazing. Didn't know I needed one until I got two!

These are the perfect scrapers. Literally. Not a thing I would change about them. I never really "understood" scraping until I got these (I'd always gone plane, thickness sand, finish" but now I get it! these are super sharp, much easier to handle than the thing flexible ones, and keep their edge much longer. Awesome for scraping binding flush to a body, too!

Ultimate Scaper

By

Verified Buyer


I bought this because I need a perfect finish that sandpaper can't give and it has lived up to the advertisement. There is a small learning curve for sharpening it but its still a lot easier to sharpen than traditional cabinet scrapers. I also save a lot of money on sandpaper. I would definitely recommend this scraper!

One of the most basic, primitive tools; the scraper.

The Ulimate Scrapers are probably the best money I’ve ever spent on tools!! I do a lot of carving, and I don’t know how I’ve ever been without them. Makes carving fun, not tedious.

New to using scrapers

I’we been aware of the use of scrapers for some time but after purchasing these and actually using them on a nice flame maple top recently I can see a future of using these more often and using less sandpaper.
