The reply I got from Strikemaster after sending them an email about the blade exchange program said that it was discontinued because it was no longer cost effective for them. Due to high materials cost and shipping they said it was becoming about the same price to purchase from a retail store.
Thanks for the input. I looked at new blades at fleetfarm it seems like they have went up from last year if i can remember right. Look like I will have to bite the bullet.
I found a local guy who would sharpen them for me and it would work great but I dont think he is in business any longer.
