Syslerigt's small knit strength gauge is a ruler and needle gauge in one.
The ruler indicates both centimeters and inches (inches), so you can measure your knitting strength according to your preferred unit of measurement or what the recipe prescribes. You can also measure your knitting needles with the holes along the middle of the ruler and see both the needle size in millimeters and US.
The knit strength gauge is made of 100% bamboo and has laser engraved writing.
