Typically I wouldn’t get that excited about a new jigsaw blade however the T308B is worth a little notoriety. Why? Basically it makes a really nice clean cut in wood. After you use them once it will seem so simple and you will wonder why all the jigsaw blades wouldn’t be made like the Bosch. For only a few cents per blade extra it’s far and away the obvious choice over any other jigsaw blade I’ve ever used on wood.  

Bosch’s patented tooth design allows the blade to cut on both the up and down strokes as opposed to most blades that cut on either the upstroke or down stroke. This dual cutting action leaves a cleaner finished surface and eliminates the need to cut from the bottom or flip the material taking a lot of guesswork out of the process.

“Most woodworkers think of a jigsaw as a rough cut that requires further finishing work on the piece. But, with this blade, these steps can be eliminated” states Mike DeMaira, Product Manager for Jigsaw Blades.

The 12-TPI blade has precision ground scalpel and pointed teeth. The scalpel teeth produce the cleaner cut on the bottom of the surface while the pointed teeth from the shank to the middle of the blade provide the cut for the top surface. The 4-1/2” blade increases productivity by allowing users to cut a greater number of materials such as hard and soft woods, MDF, melamine, plywood, and laminated particle board.

The Extra Clean for Wood blade is ideally suited for fine woodworkers, cabinet producers, or custom remodelers who need to ensure that the first cut is the best cut.

Ohio Power Tool carries a wide range of jigsaw blades for all varieties of materials including different metals, ceramic, laminates, wood and any thing else you might need to cut. If you are looking for a new fine cut saw, Bosch makes some excellent jigsaws and flush-cut saws.

Artificial diamonds are forever,
Sparkling on your little scalpel.
Unlike before they are shiner, and better:

And new Chemical Vapor Deposition method means they
Are also more defect free-ee.

OK...I'll stop and explain properly. A team at the Carnegie Institution have come up with a way of improving the artificial diamonds that are used in numerous applications, from surgical cutting edges to quantum computing. Artificial diamonds have been grown for ages, but can possess in-grown defects that have to be removed by annealing. To avoid "graphitising" and de-sparkling the diamonds, this high-temperature process has to be done at high pressures, which makes it expensive and limits diamond sizes.

The new process however uses chemical vapor deposition to grow the synthetic diamonds at low pressure (which results in "dirty" brown diamonds), and then the gems are annealed using a microwave plasma technique that heats them to around 2000K at pressures below atmospheric...turning them clear or pinky.

The result is rapidly-grown, low-defect, optical quality diamonds. Why should we care? Well for one thing one team member notes the technique may allow "kilocarat diamonds of high optical quality". Which is just cool. And for another: diamonds are used in many more applications than you may realize. [Physorg]
