SD,
Yup, we tried .125" stock, and we felt that it did add more weight than we wanted for the knife, while adding almost no additional comfort. I'll try to get a pic of my wrapped ARCLITE up so you can see what I have done. You just need to not start with the firt slot in the knife, as this will cause a problem for the sheath as you noted.
Bob Q,
There has been some discussion of alternate blade materials for the ARCLITE, but nothing firm yet. It would probally be on a limited basis for one of our distributors or larger online knife dealers. 154cm might be on the list, but VG10 would not, since it is not easy to obtain here in the US. Either way, it probally will take awhile, as we are having trouble meeting the demand of the current versions.
Thanks for your interest guys!
