Main advantages of the KMFS RIVAL MOA21 system: Complete production by CNC machining centers from a block of material for maximum rigidity and accuracy, the chassis is an integral structure made of a single piece of ENAW 7075 T651 ERGAL alloy, the entire mechanism is housed in this chassis for maximum rigidity, accuracy and durability. Patented clamping mechanism of a unique design - just by turning the clamping wheel, it automatically adjusts: the clamp to the thickness of the knife, fixes it in this position and fixes it with a double-geared system using exponential force multiplication. The clamping wheels of the clamp are precisely milled from ERGAL 7075 T651 alloy for maximum durability and service life, tied to a stainless steel shaft with a defined fixed position relative to each other. Precise angle adjustment by stepping 3 mm on the TR10 lead screw, with the possibility of extra fine independent angle adjustment of each side thanks to the patented design of the joint nuts with the function of automatic zeroing in the reference position. Equal angle adjustment on both sides by a linked movement of the left and right sides. No tools are required for clamping the knives in the clamp, adjusting the linked angle of both sides, or fine-tuning each side separately. Thanks to the movement of the joint nut along the guide screw, the effect of the increased bevel at the tip of the knife is suppressed.

The patented clamping mechanism of unique design - just by turning the clamping wheel automatically adjusts: the clamp to the thickness of the knife, locks in this position and locks in place by a double-converted system using exponential force multiplication. The clamping wheels of the clamp are precision milled from ERGAL 7075 T651 alloy for maximum durability and longevity, bound on a stainless steel shaft with a defined fixed position relative to each other. Precise angle adjustment by stepping 3 mm on the TR10 guide screw, with the possibility of extra fine independent angle adjustment of each side thanks to the patented design of the knuckle nuts with automatic zeroing function in the reference position. Matching angle adjustment on both sides by tied movement of the left and right side. No tools are required to clamp the knives in the clamp, adjust the tied angle of both sides, or fine tune each side separately. Due to the movement of the hinge nut on the guide screw, the effect of increased bevel at the knife tip is suppressed.
