StewMac Sharkskin Abrasive

About This Item

The original Sandvik Sharkskin hasn't been available in years. All of us covet the little scraps we have, and it's not uncommon to hear luthiers reminisce about using the stuff. After years of development, we have come up with a version that we think is equal to or better than the original!

Often called a "sandplate", these metal sanding sheets have extremely sharp teeth and are something between a file and a coarse riffler—fast wood removal without any deep scratches. This new Sharkskin is even better than the original because it's thinner (.014"), and easy to bend (only slightly stiffer than a playing card). The best part is, no sharks were harmed during the making of this product.

Approximately 400-grit, the StewMac Sharkskin can be bent, folded and cut into custom shapes and sizes for all kinds of guitar work:

  • Clean out old glue on a loose brace, just slide a slice of Sharkskin between the top and brace and sand away
  • Fold Sharkskin to create an angle for removing dried glue squeeze out in tight corners
  • Bend curves into Sharkskin for neck and heel profiling

1" Round Sharkskin was made at Dan Erlewine's special request. Dan uses Sharkskin and repair magnets to sand the hard to reach interiors of acoustic repairs. Just attach the 1" round Sharkskin to the magnet with double-stick tape. That magnet sands the inside, while a magnet controls it on the outside. It's easier to clean up dried glue without his arm jammed in the soundhole.

 The rounds work very well as advertised and as promoted in Dan's Trade Secrets segments.

Though I date to "olden times" and had seen sharkskin advertised in those days I'd never tried it. Seemed gimmicky though at that time I wasn't doing a lot of instrument repair. I recently had a repair on a guitar where my reach inside to the area needing attention was limited. I attached one of the little round pieces of this stuff to a 1" rare earth magnet...ala Dan E's Trade Secrets technique...and used another 1" magnet on the outside to move the inside sander around. Though I bought some of the larger sheets I haven't tried cutting them for custom applications yet. But if the performance of the little rounds is any indication I'm sure I'll find more uses for this handy, longer lasting abrasive. It is aggressive stuff and definitely not for fine sanding tasks.

Good idea, but...

I too was one of those folks who cherished my Sandvik Sandplate tool. I used it every week for years, primarily when fitting neck heels and dovetails when doing neck re-sets. So when I saw that StewMac was reviving the concept, I was interested.

After using the new sharkskin a bit I have a comment, a question and a request.

My comment is that it doesn't quite have the cut that the original did. There was something wonderful about the original Sandvik sandplates that hasn't quite been recaptured in this this revival.

My question is - how do you recommend cutting the sheets? I use tin snips but end up with curled jagged edges that have to be filed down. The circles pieces are just fine.

My request is - The original Sandvik Sandplates also included a sturdy plastic off-set tool that was designed for use with the pre-shaped sandplate sheets. Yes, it was plastic, but sturdy enough and just a bit flexible. It was the perfect tool for sanding neck heels and dovetails when doing a neck re-set - a clean cutting action and easy to control. Even when my last sandplate wore out I would attach sandpaper to the little plastic tool (though sandpaper just didn't cut like the original sharkskin) until eventually the handle broke. It seems to me that a thorough revival of the sandplate concept should include such a tool.

I gave this item 4 stars for reviving a great concept, even it isn't fully realized.

Hello Steve,
Thank you for sharing your feedback with us. Because this is a sheet-metal material, there is really no way around the jaggedness after it's cut. Like you, we cut Skarkskin with heavy duty scissors or tin snips, but then we take it to a grinder for a quick smooth edge, or you could file it by hand.

Your suggestion for the plastic tool is a great, and I've shared it with our product development team. Customer comments like yours have been the catalyst to many changes to our products. Thank you!

Great tool for teh shop!

This is a great and unique tool and can be used for hundreds of jobs in the shop. Most of the applications cannot be substituted with something else. The sharkskin is not a substitute for sandpaper. It has its own purposes. I use it mostly to make custom shaped “files”. Some of these “files” I have been using for 20 years almost every week and they still cut.

Once they stopped producing the original I bought a whole bunch. I think it was more than 20 years ago. I still have some unused original pieces. The new sharkskin is not only thinner but it does not cut as fast and aggressively as the original. The “teeth” are smaller. This is why I only gave it 4stars.

I didn't think it cut as good as regular sand paper. I will not buy it again. It may have a use but I haven't found it

Sharkskin will be one of the most used things in your shop!

In my shop we use this abrasive for so many purposes it would be impossible to list them all. It’s flexible, it’s easy to unload, it cuts fast and it’s so tough it’ll outlast every other abrasive combined! We use it on everything from guitars to piano refinishing it’s the best thing I’ve ever found!

Precise cleanup

By

For cleaning up/leveling freshly repaired bridge plates the 1" round Sharkskin on a repair magnet works great. Holds up much better than other abrasives I've used, and doesn't load up. A specialized application for those who want to do really clean, tight work.

Resurrection

By

Verified Buyer


Thank you! I was reluctant to use the pieces I had from the 60s and 70s. they are so excellent for detail shaping. the new pieces are actually finer and more desireable than my older pieces. I will most likely order more in the near future as insurance against another production gap. What other piece of abrasive would you subject to filling with shellac or lacquer and then toss it into solvent to make it as good as new?
