Far NorthWest Pacific Coast Hide Scraper, Wood an' Bone?

~4 1/2" long, ~3 1/4" wide, ~7/16" thick; weight ~2 1/2 oz. The face shown is essentially flat, but the backside is slightly convex, making for a more comfortable grip.

Plainly utilitarian in concept an' execution; its beauty, for me, is in the fine craft shown in several details: first, the inletting at the thin nose for the blade, and the relieving of the blade skirt to fit that inlet, along with the two copper pins to secure it in position (no relative movement at all). Then there is the single chamfered hole in the wood...not for hanging (I don't think) but for a thong to prevent loss, or just a wrist loop to keep the tool handy while processing the hide.

Also, of some obscure significance is the 'cushion', seen beneath the bone strip secured by 2 brass screws. On close examination, an unevenness at the lower surface of the bone can be seen at the exposed ends; perhaps the cushion 'seats' that more firmly to the wooden edge. Again, there is nothing loose there; that part is solidly attached.

The type of wood, along with the bone/ivory conundrum, are beyond my skills; marine ivory doesn't show the lines that make elephant ivory comfortably identifiable. Those two pieces show use-polishing, an' the blade has some staining. I don't think it has any deep age to it.
All your comments are most welcome...Thanks for lookin'!

 

Idle guess would be for smoothing a surface, like in a lamination process?

 

The "blade" is too blunt to be an effective hide scraper. It looks more like the squeegees used in making silk screens. But if that, I would expect it to be stained with inks.

The ends look like bone rather than any kind of ivory.

 

Maybe for squeezing water or oil out of something?

 

this item in unknown to me.......

I wonder if the wood is even from North America..?

 

The relief for the blade may have been cut with a power tool (table saw); the bottom of that cut looks dead-square to the sides. That, an' the brass slotted screws (boat hardware) put it in the early to mid 20th C, for me.
I don't see it as a squeegee, bicbw.
It came to me with 2 others...when (an' if) I come across them, I'll post pics an' further descriptive chatter right here, that's a promise. Don't hold yer collective breaths. though...

 

Ditto.

 

komo, the Contrarian...turnin' blue, jest fer yew!

 

Blue in the Face........ it's a thing !!!!
