MADE BY HAND - INNOVATIVE AND INTUITIVE FREEHAND SHARPENING SOLUTION
BELT AND POCKET KNIVES
KITCHEN CUTLERY
HATCHETS, AXES, MACHETES
BASES DOUBLE AS IMPROVISED ANGLE GUIDE FOR LEARNING PURPOSES
I have 8 kits available with more in process.
Price is $56.00 shipping included lower 48 - shipping elsewhere is $50.00 plus cost.
They come with:
One Washboard sharpening plate on wooden base - approx 2"x 8" x 1"
Set of bases/substrate anchors and four loose anchors for offhand work. Bases can be stacked to create an improvised angle guide - two bases = approx 15* incline.
4 color illustrated user's guide - now 14 pages. Electronic copy linked below of first 12 pages (to be updated).
One slug of Silicon Carbide honing compound - approx 4k JIS - Additional slugs of compound available for $8 ea
One sheet of 320 grit wet/dry silicon carbide sandpaper
One sheet of 600 grit wet/dry silicon carbide sandpaper
Small piece of pink eraser for maintaining the sandpaper in use
The videos below show how to use it start to finish. Experienced sharpeners might choose to grind their edges some other way, and only use it for a final stropping base. I believe it is still worth every penny even if used only to finish and maintain an edge. Initially that's all I intended to use it for, but realized it didn't just work well with paper, but with all flexible substrates that aren't too thick. I seldom resort to any other method now.
The Washboard is made by hand, there may be small imperfections - will not effect performance.
Send a PM through my profile page if interested, or email at - martym@merlincolor.com - first come first serve. I will be making more of these, but as I understand the rules I am only allowed to list for sale what I have on hand? Will update this listing as I go.
Thanks for looking!

CLEAN UP YOUR EDGE WITH THE WASHBOARD SHARPENING SYSTEM!
WHAT IT IS:
The Washboard is a heavily textured 2"x8" acrylic plate bonded to a wood base (custom sizes available). It sharpens and polishes using any abrasive that can be applied to a thin substrate. It can be used to sharpen and maintain a wide variety of cutting tools.
WHAT IT COMES WITH:
A genuine hand made Washboard (approx 2"x8").
Two bases.
Four loose anchors for keeping the paper taught when holding with the offhand.
A sheet each of 320 and 600 grit silicon carbide sandpaper for repair and general edge work.
One slug of silicon carbide honing compound for final polishing and maintenance of all common steels.
A few sheets of thin copy paper to get started with the honing compound.
Small piece of pink eraser to encourage good maintenance habits.
One 14 page instruction manual that will quickly have you understanding how to use your Washboard - packed with many general sharpening tips as well.
WHY USE IT:
Its versatile and easy.
The unique arrangement of ridges and relief cuts work to increase the pressure exerted by abrasive particles without an increase in overall pressure, they also compress the paper and make it much more dense - the edge doesn't sink in, rounding the cutting edge as it might with a more compliant surface. Even with relatively heavy pressure the surface remains unyielding, yet burr formation is still mild compared to grinding on a fixed abrasive. Edges stay crisp and "catchy", even when stropped many times.
The ridges and relief cuts also provide much greater tactile and auditory feedback - one can tell if they are on the bevel, the shoulder, or if they are just beginning to ride the cutting edge (if one isn't at the proper angle it will feel like they're moving the cutting tool over a washboard. The amount of feedback increases as one gets further from the ideal or target angle.). This makes it a much nicer tool than many other choices when one is trying to quickly touch up an edge, or is doing a moderate amount of work restoring a worn edge. This characteristic can also be useful for maintaining angle control when working with sandpaper or lapping films.
It can be used to polish larger areas and to maintain overall blade geometry during maintenance sharpening, touch up battered edges, do crisp work on V bevel, convex, Scandi etc, all with a minimum of steel loss, burr formation, and fuss. Best of all perhaps, its characteristics only change when you want them to - it is unaffected by loading, glazing, contamination, nicks in the surface.
Due to its light weight and flexibility, one can carry a complete sharpening setup that weighs only ounces yet has the feel and convenience of a full set-up.
BEST PRACTICES:
It was designed to work with 20# Bond, 50# text, 75GSM copy paper - these are all different designations of the same basic copy paper. Lined writing paper found in most spiral notebooks is the same base weight as well. Using it with other papers or materials is possible and can yield good results, but care should be taken.
If the paper is somewhat thicker than spec'd, it can be pre-compressed by wrapping it around the Washboard, and rubbing it vigorously with a clean dry rag or paper towel using pressure. This is actually a good practice for all weight papers. Additional sheets of paper can be used if an even softer surface is desired, such as for Scandi grinds and full convex edges, or for general polishing.
Do not store or use the board with the working surface in direct contact with a stone or other hard surface - if the teeth become damaged or smoothed out, the Washboard will still work, but not as efficiently, and there is no way to repair it.
The Washboard can be used with a wide variety of abrasive compounds, simply make certain the compound is rated for steel or stainless steel, and understand if it is for heavy cleaning or final polishing. Water-based abrasives should be allowed to dry on the paper before use.
The Washboard excels when used with sandpapers and lapping films, simply secure around the board the appropriate grit paper and it becomes a full-service sharpening system. Make sure to use silicon carbide wet/dry sandpaper, available at most auto parts stores. Remove debris from the sandpaper with a large eraser or crepe rubber. Water can be used with this sandpaper as well if desired. Lapping films coated with diamond can be used with a bit of soapy water and in this way even very high vanadium carbide or ceramic blades can be sharpened on the Washboard. For maintaining edges on all common steels, paper with compound is all that should be required.
If the paper becomes damaged or loaded, simply recycle it.
Complete instruction for use can be found in the User's Videos and User's Manual pages.

Micrographs showing some of the results in action...
Have been carrying the Jarvenpaa puukko from the WB videos since I made them, without any further maintenance - about a month and a half now. Have done an overnight backpacking trip as well as daily use since then, much of the wear on the blade is likely from cutting my daily apple and not wiping the blade completely dry, so tarnished as well as worn. many boxes, small pieces of wood, I can't remember all of it...Still, some of the edge wear is fairly nasty. The blade couldn't cut paper cleanly, wasn't three finger sticky, and could only shave arm hair when it snagged some. Due to the Scandi grind at about 24 degrees, it was still cutting reasonably well for a dull knife. One thing that I thought was exceptionally interesting is the second wear image at 1000x. To the unaided eye it just looked like it was throwing back a small glint of light - up close you can see what looks like the edge fractured or flaked off and the grind pattern just sort of stops at a worn ledge. This knife holds an edge very well, better than my other carbon steel knives for the most part, so I don't believe there's any issues with the steel and it wasn't exemplary of the edge as a whole - must've hit something that didn't agree with it. An awful lot happens over a month and a half.
In the only 400x pic, the red blob out of focus upper right is a spec of red toner - 5u average size, a bit smaller than a single red blood cell. Gives an additional feel for how short the depth of field is at this magnification.
Anyway, about 40 passes on the WB, stopping half way in to apply a second hit of compound, and another 10 or so on two sheets of plain paper - back to scary sharp. Wait for it..."CLEAN UP YOUR EDGE!"
First two pics at 1000x before reconditioning.
First one looking rough:
And looking real rough:
Now at 400x after getting worked on:
And at 1000x - totally unrecognizable, thank goodness! That knife was in embarrassing shape but made for a good experiment/QC - back to three finger sticky tree-topping in about one tenth the time it took to catch the pics.
