The quick-fire screw driver

Are you ready for some DIY? Well are ya'?

Have you ever seen a horse crumple with a stone in its hoof? Ever thought to yourself: ‘God, what I’d give to have a fish scaler right now’? Thought not. So why bother with a clunking great penknife or multi-tool that’s crammed with superfluous gadgets? Get yourself kitted out for the 21st century with a pocket tool kit full of exactly the right bits that you use every day.

the 16 screwdriver bits

16 screw driver bits

Kelvin.23 isn’t the boiling point of penknives. It’s a frisky little palm-sized multi-tool that contains everything you need to take on DIY and minor jobs, like hanging pictures, building shelves, assembling flat-pack furniture and rebuilding civilisation after a devastating global war. Assuming, of course, that the conflict left enough shelving and pictures behind.

Everything in one hand...

Some of the many functions





You’ll love having everything you need to hand in one rugged cast aluminium body: the Kelvin.23 packs in 16 different screwdrivers, a tape measure, hammer, level and even an LED for when you’re working in a tight hole, or even the flooded deck of a nuclear submarine. Those pesky fluorescents don’t half flicker on sinking subs.

This isn’t just your run-of-the-mill toolkit though: gone are the days of crushed fingers as you struggle with a reluctant screw, thanks to a locking mechanism that lets you use the screwdriver at 90 degrees for extra torque. Hard-to-reach screws are a doddle with the bit extender, while a built-in magnet holds loose screws tight so you don’t lose them underneath sofas, inside dogs, or within the soft tissue of your bare feet.

So you get 23 functions in one pocket-ready tool that’s as tough as an Icelandic docker, but as versatile as a circus dog. It even comes in a natty pink version that’s ideal for independent ladies who love DIY and hate having workshy men around the house. The only thing this 300g wonder won’t do for you is nip down to IKEA and drive your new bedroom furniture home, but then where’s the glory in that?

Customer Reviews

I orderd a Kelvin. 23 (black) multitool a few days ago. When I opened the parcel it turned out to be a powermonkey classic charger!!! I have the invoice with the item stating a Kelving. 23. I still want the item I ordered. So will you refund me the return postage? Because this not my fault! Not happy with service at all!

Bought this for my Dad for Xmas as I thought it would be a nifty little gadget for him - ANYWAY, I ended up being the first one to use it just the other day, making a bathroom tidy unit. I was incredibly impressed with it (everything worked well especially the screwdriver) and THEN I used the hammer, which dented really easily, and was pretty useless! I was really annoyed when after using the hammer, the tape measure was stuck inside the unit, (it had worked fine until then!)then after a bit of tugging, it now won't go back inside! Don't know if I had a faulty unit or not - but I would say don't use the hammer - just in case! Such a shame, I now have a useless Kelvin 23!

I got one for Christmas. Being an ungrateful sod…I don't like it! I don't like the way it feels in your hand, unbalanced and awkward. The screwdriver bits seem poorly made. One of the magnets on the side is unstuck already. Awkward to open, as has been said. Hammer is useless. Level is completely inaccurate. I found this site trying to look up the price my son paid for this piece of rubbish.

I think this is rubbish, you need a tool kit to get the screw driver bits out of the holder. I ended up emptying out all of the screwdriver bits out to get out the one I wanted, which then broke as I attempted to tighten up a screw. It's a gimmick, nice idea, bad performance. One use and now binned.

Are the screwdriver bits magnetised? If so, i'll be buying!
