Yes, you are very correct.
Based from the Blade Magazine article that I already posted on this forum, S-Tron had 14 failures on the blade, Royal Ordnance had 5 and Imperial 1. All other competitors had zero blade failures.
Anyway, for those interested I see that Frank Trzaska is selling a copy of the instructions (only one page) for the S-Tron X-M9.
