sheath
Not sure I follow that. Surely the insulation is only ever cut where the blade blocks meet it. You position the wire so the cut happens where you want it, using the stop or otherwise.
1 mm as in 1 mm^2 T&E type rather than 1 mm OD of the insulation? The reviews only really talk about T&E with passing mention of smaller stuff.Going off the CK for small stuff, which is the primary need rather than T&E. That is delt with via the cheesewire method and a cheapo "nose" type automatic that even on its lowest setting will snick a few strands of alarm wire and 50% of the time cut CW1308...
