StewMac Ultimate Scraper

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."

Great tool but doesn't replace a standard scraper

I sort of knew this was going to be good and I was right. Perfect for scraping bindings, glue build up and a myriad other jobs. Easy to resharpen on the grinder. Still go back to the card scrapers for some jobs though. On figured timber the upright angle of using this scraper seems to bring about a bit of tearout and that's when the card scraper comes into its own.

Bought primarily for lathe turnings but I know it will get a lot of use elsewhere! I bought this based on a description another turner wrote on Sawmill Creek woodworking site. BTW they have a nice instrument forum also.

There are times when it's better to remove turning defects using a hand held scraper with the lathe off. This lets you attack the grain from whatever direction works best. These scrapers are easy to use one handed and are especially useful on the inside wall of a bowl.

They are easy to keep sharp - watch the video.

Great little scraper

Works as advertised, love the size. I can put all my effort into scraping and not thinking about flexing the shape of a thin scraper. Easy to sharpen once you get the wheel height adjusted.

Scraping a viola bellies and backs with the medium scraper. Not much faster than the skinny, much cheaper blades, but somehow much more comfortable on my wrists. With the bowl like surface, it isn't as easy to scrape at 90 deg as recommended, but a little less seems optimum. The shape of the curve is nearly perfect for my higher arches would be even more so for a Strad type curve. Thanks again StewMac for a great product at the right time. Didn't give five stars because I had to make it scrape; it didn't obey a verbal.
