What makes the Economy 44-20 Thinning shear so unique? Each of the 46 teeth is precision slotted and hand notched under a microscope. This makes for a very fine cut that gives a nice invisible blending and thinning of the hair. The shear is made in Germany and warranted by Economy. We know customers who use this shear on a regular basis for decades. The 44/20 shear isn't pretty, but it is a workhorse. Note... the blade without teeth extends longer than the blade with the teeth. This is normal and is the style of the shears.
