I’ve got one exactly the same, had it 50 years ish. The blade wore out many years ago, but I’ve never seen them for sale. Avon Shaperfile comes to mind. Don't know where it is, but it’s there somewhere.
Avon Trimatool is what they were called i had one years ago but someone wanted it more than me & nicked it.
Picked up one in an antiques centre of all places in Kendal a year ago for £1.50, Bargain!
Your right, Avon Trimatool, just found mine & the name is on the handle. Needs a decent sharp blade, been that way for years, I might get one some day!Avon Trimatool is what they were called i had one years ago but someone wanted it more than me & nicked it.
