I recently bought a TS 75 second hand but it is missing the knob to tighten down the outboard splinter guard. I may be overlooking it, I have checked the Ekat catalogue but to no avail. Acme Tools lists their splinter guard 5 pack replacements to come with an addition knob, so I went to my local dealer to purchase the same pack of splinter guards (491473) but it did not contain a replacement knob. Other sites do not state that the same item number of splinter guards to come with a replacement. Anyone know how to reliably source this?
