Do any of you know if there is such a thing as a chevron or zig-zag fondant ribbon cutter?  Something like this but that would cut a chevron pattern.

Sure would make a chevron cake much easier!

The thing about chevron though, is you really have to adjust it for each tier. The height of the peaks and whatnot for one tier will not look right for another. I just have a template downloaded to my computer that I adjust and print out on cardstock for each project. Look in my gallery for the chevron cake. It's only one piece for that cake, but you can see that using that exact template for say the top tier would not have looked right. Maybe I'm just really exacting, but I would use a smaller one for that.

Anyways, get some of these, and it makes it really easy.

I'm only referring to the blades, not the cutter. Box cutter blades are longer than traditional razor blades, and are perfect for this.

Never cut these types of patterns with a typical exacto blade, rather line up the bare blades and push down to make each cut. You don't get any pulling or stretching that way, and you'll have perfectly straight cuts and lines that way.

Thanks for the reply! I understand what you mean re adjusting the size for different tiers.  I'm attaching the look I'm trying to achieve (from rosebakes.com), which is just a chevron pattern on one tier.  I'm really suprised there's not a roller/cutter out there for this, but I've searched high and low and thought maybe someone on CC had run across one.

Good tip with the blades.  I never get a clean cut with an exacto knife.

Lisa Bugeja and Flour Confections have new Chevron Cutters - they are out of stock I think (because they are only new product and VERY popular)

Not a true chevron pattern but the new Wilton Silicone molds might be OK for the cake you have shown

I have a JEM frill cutter set that came with a small chevron cutter. I used it on this cake...

Well since my previous comment, I bought a chevron cutter recently from Not Just Cakes by Annie' Etsy store. It's open ended, so you can cut as long of a continuous piece as you need. I think they're hand machined too, cause she only ever offers them in small batches and they sell out FAST! I sat and refreshed the Etsy page over and over one morning at the time she said they'd go on sale, and I barely got the order in on time.

The only concern I would have with a pre-made chevron cutter, is that it would be very difficult to get the pattern to meet up neatly at the join, as each cake will take a different number of iterations of chevron depending on its circumference.  The only way to ensure a neat join would be to get out your maths skills and work out how many of what size would fit (unless you don't mind a bit of an uneven join at the back). I don't see how a cutter could be flexible enough for that.
 

Check out this shop everyone, some really cool cutters.. here are some Chevron cutters that are closed end, but they can be very useful, you will have to just cut multiple strips and I am ok with that. I was hoping to get them from not just cakes by Annie, but again they are handmade and quantity is very limited and would be hard to get them...

these guys can also custom make cutter for anybody in any shape :-)

AAmended to add, I'll probably not use that cutter often, and opt for my previously mentioned method of printing out templates.

AOr try Marvelous Molds. They make a chevron pattern. http://www.marvelousmolds.com/onlays/chevron-onlays
