Pocket Chainsaw Makes You an Instant Lumberjack

Conner Flynn — Mon, 22 Aug 2011 12:00:03 +0000

You know how it is, sometimes you are just walking through the forest and you get the sudden urge to chop down a tree, but sadly you didn’t bring a saw with you. Well, now you can carry one with you at all times, in a little tin.

With the Pocket Chainsaw, you will always be ready at a moment’s notice if and when trees need to come down. Okay, so maybe this tool isn’t going to actually chop down any large trees, but it is handy for small jobs, like the odd tree limb that needs to be chopped.

And how awesome is it that you can carry a saw with you in such a compact form? You can have it with you and be prepared without carrying a huge motorized chainsaw. It will cut things up to 3″ in diameter super fast and measures 28″ long. The Pocket Chainsaw sells for just $25 (USD) over at Amazon.

Joerg Sprave Unveils Circular Saw Blade Flinging Slingshot, Still Has His Fingers

Shane McGlaun — Tue, 31 May 2011 23:56:46 +0000

I have talked about the implements of zombie protection that the geek known as Joerg Sprave creates on a few occasions. This is the dude behind the machete flinging slingshot and that slingshot that shoots a bunch of ball bearings. The guy is back with his latest slingshot and it is even scarier than the last.

This time around, Sprave has built a slingshot that looks like it will hack off his fingers at any second. This slingshot shoots circular saw blades down its path and they will fly a long way. The first iteration had nothing on the top to spin the blade making the blade unstable in flight. The second design had a top part that caused the blade to spin and stabilized the flight.

The saw blade is deadly at close range, it could hack half a zombies head off in one shot. I keep excepting this guy to sustain some sort of grievous injury playing with his projects. I can only imagine how bad a backfire with a saw blade weapon would be.

SawStop Does Its Best to Not Cut Your Finger Off

Technabob — Tue, 21 Dec 2010 04:02:58 +0000

If you’ve ever used a table saw, you’ve probably had the horrific image of your fingers going flying off if you slip.

The incredible SawStop system uses capacitive sensors to detect when you accidentally touch the deadly spinning blade with your flesh. The SawStop can detect skin within 5 milliseconds, and as soon as it senses flesh, an aluminum brake springs into action, stopping the blade and forcing the blade beneath the top of table. Power is instantly shut off at the same time. Your finger might get a little nick, but the injury potential is greatly limited by the system.

The technology manages to stop a saw that’s spinning at 5,000 RPM dead in its tracks. If you don’t believe it, check out this video of Steve Gass, SawStop’s creator, who’s so confident in his invention that he sticks his own finger right into the path of a spinning saw blade.

Sure, the mechanism pretty much destroys the saw blade and the mechanism in the fraction of a second that it takes to stop the blade on a dime, but I’d rather destroy $69 blade cartridge than lose my digits. And if you don’t believe it, check out these images of actual customer’s fingers which have been spared by SawStop technology.

Plus, as we learned from the video, it will also prevent hot dogs from being mangled – in case you frequently drop those into the buzz saw.

LEGO Circular Saw With Real Blade

Technabob — Fri, 04 Jun 2010 03:22:34 +0000

Keep your fingers and hands away from this LEGO creation, which features an actual motorized spinning saw blade.

Created by Dave and John Zandegar, the “Cutmaster Pro” has a LEGO brick structure, but a 9-volt battery powers the spinning saw blade and could definitely looks like it could do some damage in the wrong hands. Check out the video below to see it in action:

They’ve removed the sharpest points on the blades, and set up a safety mechanism to auto-stop if touched, but I wouldn’t want to be the one to test if that works. I’d like to keep all of my digits.

Use a Table Saw to Cut Your Cake

Technabob — Sat, 12 Sep 2009 11:32:37 +0000

Imagine the next time you have friends over to dinner, you bring out a delicious chocolate cake on the table, then proceed to hack it apart with a hand saw.

Now you can slice and dice cakes and other tender foods with the Table Saw, a serrated kitchen knife that looks just like a hand saw. Designed by Winnif Pang for Fred & Friends, you can pre-order one over at Amazon for $7.99 (USD).

Or you could just head down to your neighborhood Home Depot, and grab a real saw.

Pizza Boss 3000 Circular Saw Cuts the Cheese (and Crust)

Technabob — Fri, 27 Feb 2009 21:54:44 +0000

The Pizza Boss 3000 from Fred looks like a miniature circular saw for cutting through even the most persistent pepperonis, stubborn sausages and cantankerous crusts. Sorry, it’s not actually motorized, so mob guys, don’t plan on slicing off any fingers with one of these. (Perpetual Kid – $15 USD)

The World’s Most Dangerous CD Player

Technabob — Sat, 10 Feb 2007 13:59:34 +0000

This minimal CD player design looks really beautiful on the surface, with a case made from solid walnut and matching speakers to go with it. The design actually exposes half of the CD during playback, which seems highly impractical and downright dangerous.

While it certainly looks cool to have the CD stick out of the player, I wouldn’t want to accidentally bump into a disc rotating at 500+ revolutions per minute. The photo doesn’t show it, but I’m pretty sure the CD player wouldn’t look so slick once it’s splattered with blood from your amputated fingers.

Fortunately, the design
