I am fairly sure I used to get my swedish steel bandsaw blades resharpened - but they are for a very big professional bandsaw and are over an inch wide.Band saw is generally useful but limited in many ways - mainly throat size - and if used a lot costs a lot in blades - not resharpenable.
I ended up mainly ripping planks with a Festool TS75 tracksaw, as pushing 3 or 4 metre long boards through the bandsaw was always a bit traumatic. I also found that since the cut was so straight, I actually had less waste on the planer.
