This is another approach to a mandoline. It works very well. You can see it in action here:üsehobel-mandoline/

Great idea!
Can you adjust the thickness of the cut?

Hello Eric,
you can not adjust the thickness. But it’s perfect for cutting potatoes. We had potatoe gratin for lunch today. It was great!

Nice….I wonder if it’s possible to add an adjustment mechanism to raise or lower the blade in order to adjust slice thickness? Also, might be advisable to add a hand held piece that guides the vegetable across the blade and prevents a finger from engaging the blade! Could get ugly…

That’s nice, too bad in the US, it would take about 10 minutes before someone was suing you.

Adding this to my project list. I’d imagine coating it with salad-bowl oil will give it a decent amount of protection.

Awesome idea, beautiful project!

Great idea.
Will be making one of these.
You could probably have a couple of different slots to insert the knife into for a few different cut thicknesses.

different slots wouldn’t work because the blade has to be flush with the upper level of the board. You could fix the lower level of the board with screws, so you can put some different pieces of wood in between to adjust the thickness of cut.

I can’t wait to build this. Great idea. I actually like the fact that you designed to cut a specific thickness very well, rather than trying to make it infinitely adjustable. If I need a thinner cut, I’ll probably just build a smaller version.

I use a German knife. But are German knives different to other knives?
