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."

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

Just Like They Say - The Ultimate Scraper

By

Verified Buyer


These scrapers are ingenious and extremely useful in the shop. They can be used in curves and places that normally are inconvenient or impossible to get to.

You Did It Again!

Reinventing the wheel rarely happens, but it's been done with this tool. This scraper stands out as one of the best products to come along for a long time. Scraping binding, leveling CA glue and stripping finish is almost a joy with this tool. More aggressive than the traditional cabinet scraper but perfect for many jobs. Follow the directions for sharpening in the video and this scraper will be a permanent fixture in your shop.

This tool is ingenious! I have all three and love the ease of sharpening and the long lasting burr. I have dozens of conventional scrapers. They are lonely these days.

Exceeds Expectations

By

Verified Buyer


I took a chance in spending what I thought was a ridiculous price for a scraper that has a cutting surface barely reaching 3 inches long. I have used premium card scrapers for many years but having developed arthritis in my hands makes it difficult to bend them properly and to use a play on words holders and handles just don't cut it.
When I saw this little scraper advertised as "the ultimate" scraper I was intrigued. I read the reviews and watched the sharpening video several times. Now I've also used broken glass for smoothing for years and if this scraper would cut that well consistently it just might be what I need in my guitar making and woodworking projects. I took the plunge and ordered it and am I glad I did! This little scraper exceeds all my expectations. It rolls out the thin shavings, smoothed the wood like a dream, doesn't overheat and the real proof of the pudding: It's a breeze to sharpen! Most people give up on traditional card scrapers because sharpening them properly is tedious. This little wonder sharpens guickly and anyone can do it, from the novice to the seasoned professional. I highly recommend this scraper. It is, without a doubt, the best money I ever spent for a tool!

I had purchased the other 2 Ultimate Scrapers from Stew Mac. When I saw this new one (rectangular), I ordered immediately. I am not a luthier, but I often do detail work on boxes, frames and furniture. These scrapers are the absolute best. I reach for one of them every time I need to get in a tight spot.

Review update

By

Verified Buyer


Since writing a review earlier that downgraded these scrapers because of sharpening difficulties, I've made some progress. I feel obligated to update that review. I have a variable speed 8" Delta bench grinder. I was trying to do the sharpening with the stock wheels, with lousy results. I don't know what the grit of those wheels are, because the paper label stuck to the wheel washer and was shredded when I removed the wheel. Anyway, I recently order a 120 grit wheel from Amazon and now I find those scrapers not difficult to sharpen. I think a 150 grit wheel might even be better. I have not been able to get the perfect concave edge that Al did on the video, but flipping the scraper and sharpening both sides works. I'm a happy camper now! Slow speed and light pressure on a 120 grit wheel is working quite nicely.

Fantastic tool

By

Verified Buyer


I've been using this scraper for a few months now and I can say it's the most useful, effective scraper I've ever used - I'm quite a traditionalist so I was prepared to be critical of it but it's brilliant - takes 20 seconds to sharpen, easier on the hands, handles light to really heavy jobs - brilliant invention! I'm going to order the square one next.

This is one of the best and most helpful videos I've seen. I have a machine shop background and this is like watching a "refresher course" in tool sharpening... Thank you StewMac

Great with caveats

By

Verified Buyer


When new, far and away the most effective scraper I've used. Unfortunately, like some other reviewers, I've found it nearly impossible to sharpen. Even if you can get the wheel set up properly, no small accomplishment, and you have the right sized wheel, you need to keep the pressure and feed rate even going around the curves. Still works fairly well with less than perfect sharpening. Up next- a dedicated sharpening fixture?
