With a new and improved design, the ET9100 is a break-through technology using a toothed knife, cutting with the backs of each tooth.  The saw bends the hose into the blade spreading the cut edges thus avoiding burning and smoking.  Using a pulldown handle to allow for better leverage when cutting large bore hose, the ET9100 virtually eliminates debris left inside the hose during the cutting process.   Debris in the hose can enter the hydraulic system and clog or destroy your filter at best, and damage a pump, valve, or cylinder at worst.
