Connecticut Saw & Tool sharpens carbide BS blades, at least Lennox ones.  I would contact them or send your Resaw King to Laguna.  The teeth are precision ground; that's why they cut so smoothly.  My Lennox Woodmaster CT costs about $150 each.  CT&S can sharpen it for around $50.  As cheap as I am, I'm not going to risk trashing it for $50.

I have used the dremel trick on my 3/4" steel blades.  W/o a doubt it works really well - just take your time. 

With your blade I think you would be happy buying the dremel and diamond bit.  You have great woodworking skills  Sharpening would be easy for you.

Always use the right tool for the job.

Peter is referring to a carbide blade, which a diamond burr should cut, but that might be trickier to control.  Does anyone have experience with sharpening of carbide bandsaw blades?  

A method that controls the angles a bit better might be warranted.  Something like that shown here: https://www.youtube.com/watch?v=SoaOkqi-xxs

By the way, rather than chalk or tape, I find it handy to blacken the tips of all the teeth before sharpening by moving the blade backwards past a sharpie marker.  That makes it easy to see which teeth have been sharpened so I don't miss or redo any.  Even though most of the sharpening is focussed on the gullet, it's harder to mark there, so I don't.  The quick sweep down the back of the tooth takes off the marker.

Alan is correct about sharpening carbide..I sharpen carbide but have never sharpened a carbide tipped BS blade...It would not cause me to hesitate tho..One thing I would suggest is spending a little more time INSIDE the gullet of each tooth with the burr and avoid sliding the burr down the outside..for fear of rounding the cutting edge over a tad.... less possibility of doing that if the grinding is concentrated on the gullet..and only a thou or two should be necessary..That should make it faster to sharpen.

And at Grizzly the tool is ALOT cheaper and works just as well as the Dremel for sharpening the blades.

I have done a few and the first one made me repent on using a Dremel tool.  I now use a diamond card fine grit to do it.  It looks like a credit card and about 1/8" thick or less and use glasses and light.  I only hit the flat part of the carbide tip and the upper part of the carbide only. 
It will take longer but it will sharpen it and not dull it like what I did.

I almost thought I would have to buy another blade it was so bad but then like I said I taken my diamond card to do it again and then it worked great.

That's great, Arlin.

Thank you very much.

Have you done this on a carbide tipped blade?

I sharpen all my bandsaw blades. I have resharpened the CT below on two occasions to date ...

I use a Dremel and diamond disk to stroke the back of the blade, and leave the gullet alone. This may not work on the Resaw King ...
