While the traditional form of a pizza cutter is this…
…Japanese manufacturer Fireside has a different take, offering a much more compact form factor:
It's no surprise this Easy Roller came from Japan, where storage space is limited. But the company also says the form is more ergonomic and makes it easier to cut.
The stainless steel tool measures 95mm (3.7") wide and weighs just 100g (3.5 oz). It runs ¥1,650 (USD $11) in Japan, but with international shipping you're looking at closer to $18.
