JUST TWO: To make straight cuts, resaw lumber, and cut radii as small as 2½ in., use a ½ -in., 3-tpi skip-tooth blade. A 3⁄16-in., 4-tpi skip-tooth blade will cut radii down to 3⁄8 in.
Question:
If I start with only one blade for my bandsaw, what should it be? Down the road, what other blades should I buy?

Answer:
The best multipurpose blade for the making solid-wood furniture is a 1/2-in.-wide, 3-teeth-per-inch (tpi), skip-tooth blade made of carbon steel. As the name implies, every other tooth is skipped, or missing. This leaves a large gullet between the teeth, which allows for very efficient sawdust removal when cutting thick stock.
The same blade also can be used to saw thin stock. Just use a piece of scrapwood as an auxiliary table over the throat plate and cut a little slower.
You also can use this blade to cut a radius as small as 2-1/2 in., and even smaller if the back corners of the blade are rounded slightly with an old oilstone. This type of blade only costs about $8 and can be resharpened for about $3.50. I use BC Saw and Tool, where each order is custom made and the welds are uniformly excellent (www.bcsaw.com). A poor weld will compromise the performance of even the most expensive blade.
This first blade will cover 95% of your needs, but, for tight curves, I’d favor a 3/16-in.-wide, 4-tpi skip-tooth blade because it will cut a radius as small as 3/8 in.
One blade for most bandsawing. Large gullets are essential for clearing chips from tall resaw cuts.
A second blade for tight curves. A narrower blade will cut tighter curves, but large gullets are still essential for thick stock.

This is the saw I want in my shop. For one, it’s easy to use. All of the controls are easy to reach and manipulate, and the glide mechanism is both robust and smooth. The handle works well for righties and lefties. Then there are added bonuses that no other saw has. For instance, its hold-down is superb, as it can move to different locations, hinges for a greater range of coverage, and actually holds down the work. In addition, the saw has two points of dust collection, letting it firmly beat the rest of the field. The one downside was the saw’s laser, which was so faint we had to turn off the shop lights to see it. Still, all these pluses in a package that fits tight to the wall? That’s a winner for me.
The gauge has a quick and easy method for fitting the guide bar precisely to your tablesaw’s miter slot. This means the gauge can be recalibrated if necessary for continued accuracy. The face of the protractor head can be adjusted square to the table and also square to the guide bar. This ensures accurate cuts, and it, too, can be readjusted if the need arises. The protractor head has stainless-steel knobs and fittings and high-contrast, easy-to-read white numbers and increments.
I'm a total beginner on bandsaws. The term "skip-tooth" has me confused a bit. Take the example of a 4-tpi skip-tooth blade. The tpi is completely unambiguous, I've got that. What is not clear is whether there is such a thing as a 4-tpi blade that is NOT "skip tooth"? Doesn't it just mean a low-tpi blade, and apply to all such blades? Thanks!
I'm surprised no one else has responded to this, but overall geometry of a "skip tooth" blade is different than a 4 TPI hook tooth or regular tooth blade. All three types of blades -- skip, hook and regular--can be found with 4 TPI, but the rake (angle the tip of the tooth meets the wood), the set (how every other tooth tip is splayed a little left or right of the blades spine) and the resulting shape of the gullets (spaces between the tips) are pretty different. It seems like a little bit of an exaggeration to say that a skip tooth blade has four smaller, stouter teeth per inch vs the larger closer spaced teeth per inch of a regular blade...but that sort of gets at the idea. Hook tooth blades are named, perhaps, a bit more true to their name as they have a lot of a aggressive rake and the gullets (the space between the teeth points) are "J" shaped. Skip tooth blades have a zero degree rake so their teeth meet the wood at a 90d angle and big, nearly squared-off, open gullets...this angle helps each tooth make a cleaner "chip-like" cutting action and the big, open gullets clear the waste better than on hook or regular toothed blades. Clearing the waste quickly is important when taking these big bites as the saw dust accumulating in the kerf generates a lot of friction...heat kills a blades sharpness like nothing else.
So, if a skip tooth blade is best for nearly all ww'ing, generally, why do the other two exist? In my experience, keeping regular tooth blade around is great for rough work -- general stuff where cut quality isn't an issue like making styrofoam models, cutting up framing lumber, etc. Hook tooth blades cut very fast and aggressively and are supposedly good for cutting plastics, non-ferrous metal, , or ripping thick soft woods? I can't verify, I've never owned one. Hope this helps.

Many thanks! (I'd forgotten all about this question!)
Does anyone know of a new source for bandsaw blades? http://www.bcsaw.com doesn't seem to exist anymore.
Best all around blade is a Lenox 3/8 carbide. Expensive yes but lasts forever and leaves a great surface. Excellent product.
