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.

Fast, simple sharpening for our Ultimate Scrapers (and more!)
The grinding wheel of our Ultimate Mini Grinder is the correct diameter for maintaining the hollow-ground edge of the Ultimate Scrapers. We also added a custom steel table to perfectly support the Ultimate Scrapers and keep them level while sharpening.

These beefy scrapers are thicker than standard scrapers, and with two cutting edges they present some challenges when it comes to sharpening. If you use our Ultimate Scrapers, then our Ultimate Mini Grinder is the tool you need for a quick and accurate edge. The second wheel is an abrasive fiber that's useful for cleaning and deburring metal parts too.

These scrapers are fabulous

By

Verified Buyer


I really like using these and they stay sharp a long time. I'm also a bit lazy, so I have bought new ones when the old ones get somewhat dull. I need to learn to sharpen these. But even so they go a long while between sharpenings. And even the "dull" scrapers work pretty well. I have used them on hard tough woods and to scrape down epoxy fillings in wood with voids. The different profiles are all nice to have as each has some place it works especially well.

Not so great

Verified Buyer


Good when they are new but very, very difficult to resharpen. I have never been able to resharpen the edge. Very expensive gadget. Mostly use for scraping the glue off my work bench.

Awesome-ness

Verified Buyer


Love these scrapers. In fact, I love these scrapers o much that I have now started a petition to the Canadian gov't to allow humans to get married to woodworking tools.
I bought the regular curved one and the 'square' one along with the mini-grinder.

Note about the grinder. I am in Thailand/220v and bought a 100w converter but when I used the grinder at a higher speed the converter blew up with a great flash, well ok, a small-ish flash. I now have a 200w converter, used the grinder today and so far so good.

Splendid tool

I use this scraper to flatten ebony fretboards. So much better than a file, a rasp or a plane. Never had the surface of the wood so smooth!

Perfect for binding scraping

By

Verified Buyer


Bought this to scrape the binding on my Dreadnought Kit. Works great. Stays sharp for quite a while and super easy to “sharpen up”.
Better than my home made one for sure.
