i had a bunch of blades (4) resharpend and they dont really cut as good as as BNIB blades. is this normal? i have cut one almost complete log with this one and part of another and on wide stuff it seems like theyre already riding the back beaings. the logs (pine) are green, clean, and metal free. with the BNIB blades i was cutting like 5-6 logs on a blade.... i think im gonna order some woodmizer blades and let them sharpen them and chunk out these munkfors sagar blades. TIM I NEED U BRO!!!!!!
