In the old days labs, schools and hospitals sterilized and reused things. Nowadays, as part of cost reduction efforts they throw them away. In keeping with this trend, it is no longer possible to get regular scalpels for modelers and home scientists to use for modeling and science projects. But we have gotten some good old fashioned scalpel type blades mounted in plastic handles. They are not sterile and not suitable for medical use. But with care, they are reusable in the home environment. And item for item they are cheaper than the old type, so you may be able to break even on the venture if you use them enough. We suggest that you stock up, however, so that you have a replacement handy if one breaks, the way you used to do with blades. 6" Long OA, they come with snap off blade shields.

We don't like to brag, but it's tough not to in a case like this. This is a wonderful pen-shaped laser pointer, 5-1/4" long, flat black or silver with gold pocket clip and head. It throws a red point a loong way (we've thrown it two city blocks at night, and it would've gone farther, but buildings got in the way). And what are we so proud of? We've seen a very similar item-not identical, mind you, but essentially the same-in one of those glossy, toys-for-grown-men catalogs. Their price? $40! We're proud not to be profit-mongers, buy it here and you can take pride in your smart shopping habits. Batteries included. (Please note color change to include silver.)

So why do you want this 7-piece watch battery replacement kit? Because it's economical and will pay for itself in short order? Because you're so self-sufficient you would have removed your own appendix if only the E-R physician hadn't been so territorial? Maybe just because you want to poke around inside a clockwork?

They're in separate pockets in a plastic carrying case that can be rolled for storage or hung by its grommets. We know you'll like this kit, 'cuz we know what makes our customers tick.

The Incredible Growing Brain is grey and all ribbed and rippley like the real thing. The stem from the cerebellum is especially haunting. Incredible brain facts printed on back of package. Mom, totally science fiction, wow!

Black and white sand in a viscous colored fluid. The sand and fluid are between 5-1/2" wide x 3-1/2" high panes of glass, framed on a gimbaled stand. Flip the panel and watch the sand swirl and eddy into endlessly new pictures of dunes, drifts, mountains or moonscapes, depending on your imagination and the pattern they form. The mix of black and white creates a definite third dimension to the images. Pretty neat, as these things go.

These are the so-called miracle shears from Pakistan. They were designed for use by paramedics and others needing quickly to cut wire, light sheet metal, or other tough stuff that might stand between them and their quarry. They are normally demonstrated cutting a penny in two. Which they will do. But not as a steady diet. Let's dispel a few myths. While these are Pakistani stainless, we're not talking any miracles in manufacturing. They are good for their purpose, and real handy to have in the old tool box. But their purpose isn't making pennies into 5-mil pieces, and you will twist or break them at about the same time you find out that you've done the same thing to U.S. laws! For sheet metal or wire or fishing leaders or tin cans or whatever, be our guests.

Jewelers have the best looking tools. This ultra-slim knife is 4-1/2" long OA, with a flat metal handle that comes in assorted colors (our choice). The short, broad blade is honed to fit into the slit in a watch case and pop the back off easily. It doesn't fold into itself, but does come in a protective vinyl sleeve for storage. Very sharp.
