Is the leverage of the vertical snips different than other aviation snips?
Yes, due to the right angle of the head not being inline with the handles. Also, the way the snip must be grasped, when reaching overhead or when holding the handles upside down to reach into tight areas, does not allow the user a natural power stroke motion.
Why are the vertical snips rated for a lighter gauge than other aviation snips?
Different leverage due to a different head angle and a different way of grasping the handles, are the reasons why these vertical snips are rated for lighter gauge material: 24-ga cold rolled mild steel (0.61 mm), or galvanized steel (0.71 mm), and 28-ga stainless steel (0.38 mm).
Standard AVs or Max2000 Aviation Snips are rated for: 18-ga cold rolled mild steel (1.22 mm), or galvanized steel (1.32 mm), and 20-ga stainless steel (0.91 mm).
Is there a difference in cutting with vertical snips versus other aviation snips?
Yes, due to the right angle of the head and the way the handles must be grasped, the user will often need to push or pull the snip depending on the cutting direction.
Are any of the parts replaceable?
No.
