Phony inshaves?

[Craig Regan]

I saw this on eBay. Looks like someone is bending an old drawknive into a scorp to get more money at auction. Not sure how they work? Interesting idea but who knows what happens to the blade temper after it's heated to bend? The geometry might be off too.

Many of that kind of inshave were made by the manufacturers. That one doesn't look as well curved as most.

Sorry about the link. The inshave looks suspicious to me. It may work fine but no way to know unless you purchase it.

could have been original,or modified by a user long ago. The bottom of the curve is too flat to be of much use as an inshave. Wonder if it was made that way for a special purpose?

[Dave Beauchesne]

Would the handles have hot been ' canted ' outwards a bit if it started life as a straight shave?

The handle geometry looks decent for an inshave - the collective mind trust may come up with an answer.

There were a couple of makers who produced inshaves like that one. I've seen a few over the years at the LFOD actions. You are correct though, they are of limited use as a scorp for scooping out things like chair seats.

That shape is actually a popular one for chair makers. The corners are used to make the steeper sections at the back of a seat. The flatter area is used to make the less steep seat sections and transitions.

The inshave above is a model Drew Langsner, author of multiple books on green woodworking and chair making, has custom made. The design of the blade helps the user to make all the various concave areas in chair seats. Peter Galbert mentions the value of inshave/scorp blades shaped like this in his new book "Chairmaker's Notebook". Pete prefers this shape. He believes the inshaves with steeper angles can often cause tear out and remove too much wood.

A Cooper's hollowing drawknife is also similar and has the handles extended out past the functional/working edge. Similar tools may be seen at Country Workshops, .org. Similar items are sold there so I want make a link.
