pizzaguy:
I have one and use it sometimes but I find I can cut faster with my knife and just about as accurate. But it is great for beginers. Mine is an eight cut for up to a 14"
These things remind me of the “Healthrider” I bought a long time ago … looks really cool & useful for a while, then never gets used, except maybe as a coathanger. What I do is take a little more time cutting each pie (the school that we have a regular deal where they resell asks for a 10 cut) and send them an extra pie for every 20 they order. Rather than being unhappy that there’s a couple slices that are a bit small in comparison, they’re thrilled to get the extra pizzas that they can sell at no extra charge! Yeah, they’re probably selling all of it at full price, since we’ve got the “10 cut” pretty well down now, but I’m still making good money off it & they’ve found that they can sell more than they thought - they normally buy 10 more pies each week than they did 2 - 3 years ago.
Just slow down when you’re cutting a little bit - for an 8 cut, you should be able to make virtually every cut perfect - for a 10 cut, try this …
Use a cutting board for the pizzas, using a screen, etch around the outside of the surface. Using a 16" screen should give you a perfect 16" circle. The circumference of a circle is pi * Diameter … 50.27 inches for a 16". Measure along the arc 5 1/32 inch to place each cut mark. According to the formula, your last slice would be a bit small, but since you initially draw around the outside of a 16" screen, the actual diameter will be just a c-hair more than 16" - you ought to come out all right. Once you have everything perfect, mark the circle and cutting lines with a non toxic permanent marker (Marks a Lot markers I know are ACMI certified as non toxic).This should be just as accurate as, and a lot less hassle than, the contraption you’re thinking of.
Good luck with the job! $30k a year? Dang, I’ve gotta find me a deal like that!
