A Chisel For Hard-To-Reach Places
By Benjamen Johnson
This odd-shaped chisel with two blades rotated 90˚ to each other allows you to cut square-sided mortises in tight places you’d never be able to reach with a conventional chisel.
Chris Becksvoort designed this modern reproduction of the traditional drawer lock chisel, and Lie-Nielsen manufactures it with 0-1 tool steel and precision-grinds it here in the USA.
You’ll pay $75 for a pair of these chisels. We’re not sure why Lie-Nielsen sells these chisels in a set of two — from the picture we can’t see much difference between ‘em. Maybe somebody can give us a clue in the comments.

Mirror image. The one head is completely symmetrical and could be used either way. The vertical (lower head in the picture) would have to be a mirror image to get both sides of a recess.

I would surmise that one is a left hand and the other a right hand. When working in tight spaces both would be required depending on whether you were working bevel up or bevel down. When cutting mortises, a greater amount would would have to be removed and plus needing to square both ends.

OK, now I understand, one chisel head for each of the four sides.
Thanks Corwin and Harley130

I have an old one manufactured by Spann Sage.
This pair - like most Lie Nielsen products looks like the took an old design and did it one better

Can’t see the…! One is a left and the other a right bevel, no?

but it looks like both chisels top heads are beveled the same way. flat on the top and an angle to it on the handle direction.

If you watch the video they have demonstrating these, you can see the application where you’d need both the left and right. In order to get to both sides of a rectangular (or square) mortise in a closed box you need the the flat spot of the blade to be on opposite sides.
