Thanks Vince.
Advice sought about a tree type ,its various values and charactistics and the worth of salvage instead of chipping and convenience cutting/milling etc.,is much appreciated.
Of course you have to know stuff outside your saw sharpening. Cheers, Sean.

We used Geraldton Saw Doctor to sharpen our knife set. Vince did a great job. Our knives are shiny and super sharp. We were offered a substitute knife to use while ours were being sharpened. That was thoughtful customer service. Would highly recommend.

Approximate cost: $50
