These are Brand New Blades - never mounted or sharpened.  The customer got the wrong size and exchanged them for another pair.  

Matrix is up to 33% lighter than traditional blades! 

Reduced weight means reduced fatigue and with stainless steel runners, our blades have harder edges to hold edges longer.

All pick patterns are identical to those on our Ultima blade models, allowing seamless transition.
AUS8 Stainless steel runner is maintenance free and holds edges longer for a longer lasting blade.
Runner is inset into chassis and permanently secured using 3 axels.
Parallel chassis allows for accurate sharpening.
