What's the best kind of soap shaver?

[The_Emerald_Chicken]

I'm considering buying a soap shaver for trimming up finished bars of soap. I think it'd come in quite handy for things like removing soda ash and silicon rash. For those of you that have one, do have recommendations of a good brand or place to purchase one? I've used a vegetable slicer in the past, but it doesn't give me uniform cuts.

This is the idea of what I'm looking for:

I have what looks to be that exact one. It's probably not completely perfect, but I'm pretty happy with it. The only thing I would prefer is a side fence to run the soap along to get an exact right angle or 45 degrees for planing or beveling, but other than that no real complaints. If it's the same one there are a couple of screws underneath which you can use to adjust the depth of the amount planed.

I replaced my wooden one just like that one with an acrylic one. After a couple of years or so if use, the wooden one started leaving grooves in my soap (from a warped area on the wooden surface).

Not this exact one, very much like it: Acrylic Soap Planer
