Hi Andy
No, I haven't used Hegner's own reverse tooth blades. I went to their stand at the Midlands show a couple of years ago and asked if they had any blades like that, only to be sent away by the bloke running the stall. He told me, in a very loud voice, that there was no such thing as a reverse tooth blade, nor a skip tooth blade. The stand was crowded at the time and everyone stared at me - it was very embarrassing. I knew the bloke was a . but it was difficult to show it on the spot because it would have been the word of a punter against an apparent 'expert' :x .
Yes, I was thinking it might be an idea to run a cutting trial similar to Alf's. I'll also have to get some blades from B&Q or similar to run a proper comparison and use a variety of materials. It should be interesting. If anyone knows of any other blades they'd like me test, let me know which ones and where they're available.
I was delighted to learn that the Arnold Laver website shows them as having 1.5mm and 2.0mm thick Finnish Birch plywood (111 grade, whatever that means :?: ) and they have a depot nearby in Kidderminster

. I'll have to pay them a visit.
Oh happy day! I've just had a phone call from the driver of the waggon that's delivering my new workshop, asking for directions
