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,

By

I bought this tool because my aging thumbs are no longer happy bending a traditional card scraper to work on mandolin tops and backs. This new tool is wonderful--super sharp, stiff (no bending required or possible) and offering almost limitless curved surface edge to help establish the recurve profile I want at the outer edges of tops and backs. Easy to use, versatile, easy to sharpen, hard and very durable. Nothing but praise here. Wish I'd gotten this tool long ago.

Amazing little helper

This was a great addition to my growing set of guitar building tools. I truly never expected it to perform as well as,it does. I recently took on my first build with a carved top and this was the primary tool that I used for the entire shaping. It works amazingly well, it's easy to get the hang of and holds a good edge for a good long time. For anyone needing to carve a top or a neck, I can't imagine doing it without one of these in your arsenal.

Good Luck and God Bless,
Dave

I'll keep this nice and short: I haven't used my traditional card scrapers since using this tool, and I'm not sure if I ever will.

Super scrapers

By far the best scrapers I have ever used. The method of use is a bit different than the typical scraper but it only takes a few minuted of practice to be using them like a pro.

The best scraper ever

I have used scrapers for years and really never liked the thickness of the card type scraper. This scraper has the weight and feel of a tool I want to use as opposed to finding other options when my fingers are too sore to handle the thin type scraper.

Ultimate Scraper

This scraper has the aggressive cutting power that's needed for my coopering work. I build curved cabinet doors and it's perfect for smoothing down the points of the staves. I like it so much I'm making my own for the concave large jobs.

I have been a woodworker for more than 40 years and I hate to admit but sharpening a traditional card scraper has always been something that has eluded me. This scraper is totally new and different. Great tool.
