Shaft Knife - Split Clamp-on Rope Cutter

Split clamp-on type propeller shaft rope cutter. No need to remove the propeller when fitting. EFFICIENT Manufactured in high quality 316 stainless steel the SHAFT KNIFE works when it's needed and cannot suffer from shear loads. Other devices have passing cutting edges which can cause shear loads when cutting and this can be disastrous if a solid object is encountered. AFFORDABLE Due to its simplicity, the SHAFT KNIFE is a low-cost product and does not suffer from complicated bearing replacement and maintenance. It might occasionally require sharpening. EASY TO FIT Remove the propeller, dimple the shaft to locate and fit the SHAFT KNIFE and replace the propeller. It's as easy as that. No special tools required and no boatyard charges for fitting.
