As all these posts about the legitimacy of my tools make me a bit uncomfortable, I dare to add my point of view to the discussion.
I perfectly understand that not every woodworkers need such rasps, and that it is possible to acheive good works using other techniques.
First I have to state that despite the possibility that some person may think these tools are overpriced, the wages of my companions or myself don't make us in an easy position if we were to buy much of these rasps.
Please watch the short video on my website showing how these rasps are made, it shows that the number of hours we spend on each rasp to transform the steel bar into a finished tool having between 5.000 to 10.000 teeth, may justify to you its price. Another justification could also be that there are woodworkers that are appreciating and respecting the efficiency of the tool once they have had the opportunity to actually test it by themselves. This is the reason of this free pass-around test. So, as Gareth offered, I would be glad you join the test.
