When you saw wood, metal or other materials with any tool (skill saw, band saw, table saw, saber saw, and other bladed cutting tools) if that tool is not a standard chain saw then the blade always will continue to dangerously spin after the cut is made. There is only the protection of guards that slowly close behind the material you are cutting. This means that if the guard fails (and they often do due to sticky or jammed guards etc.) then you can seriously hurt yourself. If we place disc...

Just imagine the thousands of uses a handy pocket sized razor knife would have if you could simply put it in your pocket or fit it into your wallet. A knife that could easily be hidden and no one would know that you have it on you. A self defense mechanism or a tool with many uses. Handy on hiking trips, hunting, car repairs or cutting anything at all. It could even be a serated edged knife for handy sawing action. It could serve with many components of a Swiss Army knife if you only fit...

You could go from airport to airport or anyplace in the world with Swallowable Computer Scanable Capsules. You would get your subscription from a pharmacy that is in connection to that particular government in your country and you could be scanned and be on your way very fast. It would have a prescription of pills that lasts until you come back. They could also be able to tell, by adding to the small computerized pill that you've been approved by another country to enter that country....

What would be better than a regular crayon? One that fully saturates the paper in full vibrant colors that fully cover a page and leave no lines behind. Very little effort to use a liquid wax crayon pen that brings out the best colors ever. Just like a pen or ink the pen can come in different sizes and they could glow in the dark or be flourescent colors or any kind of materials added to the wax. This product is related to different paints and white out type products that can be flow...

Since all condoms (big or small and all inbetween sizes) come in a case of approximately the same size you could easily slip any condom into your (nicely sized) key chain. Most key chains that are see through plastic come with the option of adding or removing a photo, but if we enlarge the slot we could fit in our condoms where they can easily be displayed everywhere we go to show the whole world we plan to play it safe and it wouldn't get old and bent in our wallets. A fast way to get...

Detachable, retractable (it goes up to the top of the regular bike helmet or down in front of your face) face shield much like the face shields worn by police officers wearing riot gear masks but, with much lighter weight (thin but, strong clear plastic). Not for impact protection but, has many other protective features such as pebbles, bugs, wind burn, dirt, dust, or other flying debrise protecting all parts of your face especially your eyes from abrasion from objects in the air (dust can...

Have you ever dropped a two hundred dollar fishing pole and it went three hundred feet straight to the bottom of the lake or Ocean? Well, if that pole floated then you could just pick it back up without having to stop your vacation to go back to the fishing shop and spend your hard earned money on some cheap imitation of what you had all your life or one your family heirloom handed down throughout the years. If the pole floated with an inner core of floating foam or an attachment you...

When you boil or cook something in a pot, it will overflow whether you are watching it or not, and it usually does it when you're not around to watch it. If you add a second connected pot with a thicker bottom on the outside both connected at the bottom of the first pot, that will prevent burning. You add a lip to the inside pot into the outside pot (for overflow) the heat from the outside connected pot will super heat any overflow, preventing danger and most of all a big mess.

I hate to go out every year and have to pick out a new calandar! Why can't someone make one last for fifty years so that people like me can hang them on the wall and when they drag you out dead in fifty years they would find the only clean spot in your place would be behind your fifty year calandar. Why every year? Why a desk calendar? I don't want a one year calandar and I don't think you can write on a desk calandar. Just make the pictures different for each month, make them good...

We should consider using a Universal word to rename our planet rather than using old words from thousands of years ago to bring all countries together under one word, instead of a translated version of the word Earth. Besides, it is not a creative word and it is old. Like all new things they are usually rejected at first since old words are comforting, and changing the word for Earth means changing it whereever it is written. (Books, maps, etc.). But other words are changing and after a...
