Brought my Shawn shim and saw tooth knife to my dad’s to show him how hand cut dovetails work. We were both kind of blown away that a gapless joint, right off the saw, was possible for two hacks up late on a Saturday night.

I use the 0.025" kerf blade with my Lie-Nielsen (0.026" kerf) and Tyzack & Turner (0.021" kerf) DT saws. The combination is perfect as long as you don't go too deep setting the initial kerf in hard woods. Let the kerf knife set the line and let the saw cut the pins.
Perhaps I'll get a second one for the finer saw

I was pleasantly surprised by the heft of this knife, both the blade and the kerf blade are very stiff and well made. I have a number of marking knives scattered throughout the shop and I can see this one becoming a favorite.

I suppose it would be totally awesome if the extra blade could be stored in the handle...but maybe just getting a second one is a better option.

When I saw this marking knife, I thought, “That looks clunky and uncomfortable to hold.” However, I liked the idea of starting the kerf from the marking knife, so I decided to try it. I’m happy to report that my initial reaction to seeing the knife was wrong because it's incredibly comfortable to hold and well-balanced.

Adds a great deal of accuracy especially when using to mark for pins when cutting dovetails.
