T2 and ultra-concave blade

[gwelsby]

Hi, all.
I have a VERY concave carpet/lino knife which I have been trying, without much success, to sharpen on the rounded wheel of my T7. It appears to me that with the T2 I could simply draw the blade through keeping it perpendicular to the wheel at the point of contact.  Is this correct?
TIA,
Gerald.

Probably not... the guide on the T2 just draws the blade across the flat of the wheel.

I agree with CB. If I was in your situation, I would make a trip to the local hardware store for approximately three feet (one meter) of plastic pipe, conduit or wooden dowel. The exact length is not critical, nor is the diameter, around 1/2" or 12mm. Get some wet or dry sandpaper, either adhesive or regular. Either will work. With the regular w/d sandpaper, you will need some tape to secure it to the dowel or plastic pipe. Cut in three or four lengths to make "files". Sharpening your knife will go quickly.

ps Life is easier if you save these files and retouch your knife when it just starts to get dull.

Thanks, CB. I've ordered one anyway so I'll report back when it comes 😀.

Thank you Ken. That would let me sharpen at its current angle. If I wanted to choose the exact angle myself?

Gerald,

I would use the "sanding sticks" with the marker, favoring either the edge or the back of the bevel. As long as the knife is sharp, how"exact" does the angle need to be to cut carpet or linoleum?
