Kwik-kut Food Chopper

Chops almost any food item

As a kid, I helped my mother cut out biscuits with this cutter. When I saw one at an estate sale a few years ago, I snagged it. It was only then that my mom let me in on a secret: this tool is useful for so much more than cutting biscuits. She uses it instead of a pastry cutter to make pie crust and biscuit dough, plus chop strawberries, nuts, and vegetables. Sure enough, I haven’t used a pastry cutter since. With just one circular blade, it’s much easier to clean than a pastry cutter with its multiple blades that always seem to get gummed up. Last time I made strawberry jam I used it to chop the strawberries a bit, and it worked so much better than my other options: a knife, which would have taken too long, and a food processor, which would have turned the strawberries into mush. It’s still my go-to cutter for biscuits and is just the right size for donuts. The cutter is made in America and will last for decades. My mom has had hers for at least 35 years, and it still works great.

Show notes:

4K TVs as computer monitors
“[I have] a 50-inch 4K television, and you may think, ‘Wow, that’s really big, how far away do you sit from it?’ I sit the same distance I sat from the 30-inch and the 24-inches that so many people use. In fact, if you think about it, the typical 24-inch HD monitor, that is the most common sort of monitor sold today or a few years ago, that actually is one quarter of 4K and it’s 24-inches, which means it’s basically half of the 50-inch screen. … The great thing though is, they’re selling these TVs really cheap. They’re selling them down, you can get them for five, 600 bucks, even less …They didn’t want you to use these as monitors, they designed them to be TVs. So there’s s few tricks to pull, but if you do you can get something that’s just amazing.”

“I run a voice over IP PBX in my home, that’s a little unusual. You may not need to do that, but there are lots of voice over IP services now, so you can get even your landline phone to travel with you. No matter where you are in the world, even on your cell phone or on your computer or if you want to bring a small phone with you because you like that landline experience, which I happen to. I like the voice quality and the physicality of it for a real conversation. You can get that and proxy it up so that my phone in California, you can call it, and it’s gonna ring at my desk in Paris and I can call you back. It’s gonna look like I’m there. A lot of people are doing that.”

Fire TV Stick ($40)
“I brought [overseas] my Amazon Fire Stick. I have the first generation one, that was my mistake. The second generation one can be programmed to do what you need to do here, which is use a VPN, a virtual private network. Why? Because you want to cheat all these global content controls that are telling me, even though I have an American Netflix account and I’m paying money into it right now, Netflix will not show me the things that I pay for in the US, ‘cause I’m in France.”

Sony cameras
“I like the fact that my cameras keep getting smaller. … I’ve got the Sony a7RII, that’s about the best of the digital SLRs for image quality right now. Now, Sony just came out with their A9 which is possibly better. And then in their line I have their APS-C size, that’s the sensor that’s about half the size of a full 35 millimeter frame. That drops a lot of weight. … I also have, again it’s Sony so this one doesn’t have to be, but it’s one of the nicest little point and shoots. That fits in your pocket, and it’s the DSC-RX100 IV, and that guy does get some great images. But of course it just has a point and shoot zoom lens on it.”

Starship Technologies
“My favorite tool I’m working on right now is with a company that’s based in Estonia, and it’s called Starship Technologies. We’re making a delivery robot. It’s a little robot the size of a big beer cooler, and it’s got six wheels, and it’s not fully autonomous yet, but it’s going to be. It’s going to bring you everything that you want to order in 30 minutes, and it’s gonna cost under a dollar to do it. … Like so many things these days, you won’t be able to get one. You’ll be able to get one to bring you something, or if you’re a delivery company you might be able to buy them. “

Maker Update: Kreg Rip-Cut

Speeds and simplifies ripping down large plywood and MDF panels

This week on Maker Update: LEDs for your eyes, talking to your lamp, a new marble machine, the poor man’s table saw, and a giant super soaker. Show notes here.

This week’s Cool Tool is the Kreg Rip-Cut. It’s a $32 guide for a circular saw. It’s great if you have a small workshop, or no workshop. If you have a table saw, there’s probably no reason to buy this. But if you have a small garage like mine and you don’t want to surrender the space and money to have a table saw, this and a circular saw are an effective way to accurately break down sheets of wood.

It comes in two pieces. One is a universal adapter that can mount onto just about any circular saw — including left handed ones. This just screws onto the existing plate, and I just leave mine on all the time.

The other is this L-shaped aluminum ruler designed to hug and slide against the straight outside edge of your wood. You latch the adapter plate onto the ruler, measure out where you want your cut, and make it happen, using the edge of the board to guide your cut.

Now, there are two obvious limitations on this. One is that the aluminum guide only extends out up to 24 inches. The other is that you’ll need some kind of spoiler board if you want to cut all the way through your material.

Alternatively, you could buy a long metal guide track or even use a long 2×4, and clamp it down wherever you want and let that guide your cut. But, using the Rip-Cut, there’s no limit to the length of your cut, especially with a battery powered saw. Also, if I want to rip another, identical section, there’s no setup. I just move back to the beginning.

Even more important for me, I don’t have to store a big, long, metal track in my workshop. This thing just hangs out of the way, and it’s small enough I can just throw it in my back seat if I need to take it somewhere.

Extreme Duck Tape

Compact emergency tape

[This is a Cool Tools Favorite from 2003 – MF]

As part of my ultra-lighting up of my backpacking gear, I stumbled across this cool repackaging of duck tape, perfect for hikers. The tape is “flat-packed” to save space, and the extreme version has super-bright write-on colors. A (nerdy) backpacker’s dream, certain to become a fixture in my fix-it kit.

Lock Laces

Elastic no-tie shoelaces

I am not a good shoe tie-er. For years I have wanted to get Velcro shoes, but my wife won’t let me because she says they’re for five year olds or for eighty five year olds and I am not one of those. About a year ago a friend of mine told me about these elastic shoe laces.

Lock Laces are like bungee cords. You lace them up one but you don’t have to tie them. They have a little lock and you lock them in and they are as tight as your regular shoe laces. I haven’t tied my shoelaces in about a year and my wife doesn’t yell at me or walk ten feet ahead of me because they kind of look like normal shoes laces.

Hennessy Tent Hammock

Light, quick cool shelter

[This is a Cool Tools Favorite from 2003 – MF]

An ultralight gear item which I’ve been trying out is the Hennessey Tent Hammock. Part tent, part mosquito mesh, part hammock, the thing is pure genius and a pleasure to use — very light, ingeniously designed, and actually provides a comfortable backcountry sleep. Perfect for wet areas. You do have to worry a bit more about insulation under yourself, but not a big minus especially given the comfort of the shelter.

— Rex Ishibashi

Hennessy Hammock is a brilliant fine-tuning of the hammock concept into a tent substitute. It means I never have to sleep on the ground again! Being asymmetrical it allows me to lie relatively flat for a very comfortable night’s sleep. There is a large rain-fly that cocoons around the hammock in cooler weather, a fine insect/dust mesh enclosure, and an entrance that my weight closes behind me. You can even set it up on the ground like a bivvy-bag if there are no trees (or lamp posts, or bumper bars). Great for tropical camping.

We Refreshed Our Website

If you read Cool Tools via RSS (which is the way Kevin and I read blogs) then you probably don’t realize we updated our website design today. We took your feedback seriously and tried our best to simplify the design and make it more legible.

I’m sure we got some things wrong. If you find a mistake or have suggestions about our current iteration, please let us know in the comments.

Thanks for reading Cool Tools and being part of the community.

If I’ve still got your attention, I’d like to remind you that Cool Tools runs reviews written by our readers. Please recommend a tool you love.


Cool Tools is a web site which recommends the best/cheapest tools available. Tools are defined broadly as anything that can be useful. This includes hand tools, machines, books, software, gadgets, websites, maps, and even ideas. All reviews are positive raves written by real users. We don’t bother with negative reviews because our intent is to only offer the best.

One new tool is posted each weekday. Cool Tools does NOT sell anything. The site provides prices and convenient sources for readers to purchase items.

When Amazon.com is listed as a source (which it often is because of its prices and convenience) Cool Tools receives a fractional fee from Amazon if items are purchased at Amazon on that visit. Cool Tools also earns revenue from Google ads, although we have no foreknowledge nor much control of which ads will appear.

We recently posted a short history of Cool Tools which included current stats as of April 2008. This explains both the genesis of this site, and the tools we use to operate it.

13632766_602152159944472_101382480_oKevin Kelly started Cool Tools in 2000 as an email list, then as a blog since 2003. He edited all reviews through 2006. He writes the occasional review, oversees the design and editorial direction of this site, and made a book version of Cool Tools. If you have a question about the website in general his email is kk {at} kk.org.
