This compact marking gauge is an ingenious scribing tool for wood joints, small wooden objects, model making and craft carpentry. It can be fitted with a straight or disc-shaped scribing knife or a needle, according to preference. The fence, which is locked in place with a clamping sleeve, may also be adjusted with one hand; its asymmetric shape makes precise scribing possible, even on thin workpieces. Includes 12 straight blades, 1 disc blade, 1 needle.
