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.

#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."

Easier than expected

Used the original size to scrape some tortoise binding and a rosette, and the results are outstanding. No chatter and such a smooth cut. Well done!

Fantastic Scraper

I bought this scraper for instrument work, but it has really proven itself in inlay work for some furniture projects. Stiff, durable, and holds its edge much longer than a card scraper. First class!

The Great (E)scrape!

You never really know when you purchase an item from another country whether it will live up to expectations when it arrives. I have only done some test runs with it so far but the Caruth Utimate scraper is a gem. Beautifully made, easy to use and does a fantastic job.It should be in every toolbox.

Carruth Scraper

If you use scrapers you have to get this one for sure, it removes 50% more wood then a thin card scraper and is so easy to use I love it.

The Way to Scrape!

I learned to scrape wood with a wide, thick metal scraper made from blade steel. I resorted to the thinner gauge scrapers that have been available, but was never satisfied until I got the Carruth Ultimate. This scraper has comfortable mass, stays sharp, does flats and dishes. Next purchase: the Mini for the small bits. Thanks for making these available.
