I am going to jump into another direction. Have you considered the Wensel Woodsmans? I have used Magnus in the past and they were okay, but I really like the look of the Wensels. The Wensel is a three blade head so using a lansky may not get the job done; on the other hand I have read numerous postings that say the Wensels hone up very nicely with a good file, and the hole produced by the three blades is without exception. I will let you know as soon as I get home and purchase some.
