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."

Awesome scraper

I opened the box, saw a nice velvet pouch, and inside, THE scraper.
Tried it. My life will never be the same. Nothing else to say.

Not so good

By

I’ve used card scrapers in my wood shop for a long time. My aging and arthritic hands suggested I try this scraper...no need to flex the card. But, alas, I can’t make it take a shaving no matter how I sharpen it or use it. Three stars because it’s well made.

you will need a perfect grinder

I build archtop guitars and some flattops too. This is no better than a hand-sharpened simple and cheap scraper. it is easier on the hands as you don't have bend it while scraping. The edge it is supplied with is ok but not sharp enough to really cut. I use a horizontally turning water stone for my initial grinding step on my tools. My other ginder wheel is not smooth or precise enough to sharpen this so this little expensive tool is just sitting in the cabinet largely unused. It is great for rough work such as scraping finish off. If you want to get the most out of this make sure you have a perfect electric grinder in your shop suitable to grind this tool.

Performs VERY well - watch the video

After watching the video demonstrating it's use and how to sharpen it, I bought one (the original). Steel is nice and hard, so I haven't had to sharpen it yet, but it seems easy if you have a fine grit low speed grinder. It did look a little smaller than I expected, but after using it, it's really a perfect size and shape. I might never use a card scraper again, and I was just getting good at sharpening those!

Nice change over classic card scraper.

By


I've been using card scrapers for several years, and stumbled across this one. While pricey, it is pretty easy to sharpen, and easier to use than a card scraper. There is no need (or ability) to put a bend in the scraper (maybe the Hulk could), and it does a great job. I was just using it tonight to finish the contours on the body of a '51 PBass I'm making. Most of the contour was done with a spoke shave and rasp, but all of the cleanup was done with this scraper. I did find that the long flat edge was slightly concave, and spent the better part of an hour fixing that on some diamond stone and sharpening on the grinder. After that, it worked beautifully! A nice addition to the tool chest.

Nice tool

I like using scrapers and do quite a bit. I have an assortment of good card scrapers and didn’t think I needed another one, but gave these a try and am glad I did. They’re easier to use one handed and the thickness of them make for an effective, solid scraper, especially when sharp.

Careful with rectangular scraper

By

Verified Buyer


The rectangular scraper can hawg away wood like a smoothing plane, and is great. But, if you accidentally use the concave side on a top or back, you’ll immediately do so much damage that you’ll have to throw the entire remaining pile of wood into the scrap pile. Seriously! StewMac should round over those edges a little bit—they will eventually ruin someone’s day.

Great tool.

Very stable. Different from a standard scraper so it takes a little getting used to. Very slick tool.
