The proper name for this is “Nihon Sao Suji Kebiki Dai” which, loosely translated, means ” Go to your drawer and find the smallest and loveliest of your saved wood scraps and see if you can’t make a passable tool out of it”. So I did.

I don’t really know what the body is, Kingwood perhaps? but what I do know is that I didn’t have quite enough to do the job. That in itself was fortuitous, for by laminating padauk to the bottoms of the arms and using it for all the trim pieces I am far happier to have it in my hand and in my sight. No Zen master here, just following my accidents.

I press fitted a huge threaded bushing into the thin body (careful!!) and pinned a 1/4 – 20 bolt to the double arched wood end. Drill through both, snap off the drill bit and grind flush. The end of the bolt was freehand ground down to a small tit that seats in the centre of a #1 Robertson machine screw in the pressure plate. This plate pivots ever so slightly to take up any inaccuracies.

The marking/cutting knives are snapped off sections of black (super sharp) Olfa disposable blades. Always keen, always available, and Japanese to boot! There is an imperceptible bias on these towards the fence, keeping it tight to the work. As I use this tool only on flat stock the fence was made quite low and thus able to mark very thin pieces while still on the bench. The finish is shellac and wax.

Oh yes, I did screw up badly as you can see in the last picture – the bottom face was glued on backwards. Which, loosely translated, means I’m a real doofus sometimes.

looks like a great tool! Wish I had the time/wood to make my own homemade tools. Being a poor college kid, i neither have the time or the money (wood) to do this! This is an inspiration to when (some day) I DO have the means of actual fine woodworking! haha. Thanks for sharing!

I’d bet the farm that is Ziricote. It looks beautiful. Nice work!

That is a beautiful “Nihon Sao Suji Kebiki Dai”, beautiful wood what ever it is, and some really crisp details.
I love it if you have any doubt.
Best thoughts,

Beautifully executed despite your mishaps. I agree, that the dark wood looks to be Ziricote, as this species is known for the domed grain pattern seen here. The Padauk gave a nice red tone contrast to the blue/yellow of the Ziricote.

I have tons of interesting scraps, if only the inclination to create such a tool! Could we see some “action” shots?

Is one allowed to use “fortuitous” in the same description with “doofus”?

Very well done,

well, I’ve favorited this to add it to my “to-do” list. I always wanted a tool I couldn’t pronounce. Making my own is even better. Beautiful job.
