Hi Charlie
Back from my holiday in Nice, France hence the delay in replying. What weather and what a lovely location. Will certainly be returning.
Thanks for the comments about the models. Sketchup certainly does the job for me.
With regard to the Japanese marking knife section. Originally there was a link to those pages but since I have been paid by British Woodworking for the information I felt that it would be wrong of me to then provide the information for free.
The method of using the front edge of the knife I came upon by pure accident whilst working away one day. For me it is the most efficient method of marking a shoulder line.
If you want further info on this I would happy send the stuff through via private email.
cheers
Alan
