Rosle Stainless Steel Egg Cracker

Having spotted this product it seemed to be the ideal thing to use to crack a boiled egg so ordered one. When I first used it I pulled the handle to its fullest extent and when I let it go it not only cracked the top of the egg but the rest of the shell as well as the spring is very strong. Might work on a fully hard boiled egg but defiantly not on a soft boiled egg as you need to be a lot more gentle on how high you pull the handle before letting go. Have been getting the hang of doing a number of lighter taps on the egg to crack the top rather than shatter the entire shell but it is still taking time to master the correct pressure required.

Smaller than I expected at about 15cms/6 inches in length, it consist of a bell which fits over the pointier end of the egg, and a 'T' shaped handle which pulls up. Hold the bell on top of the egg securely but not too firmly, pull the handle up to its fullest extent and let go. There is a clack sound as the handle hits home and the lift the unit away. At this point either the complete top of the egg will come away, or just the cracker - leaving a neat line around the egg where one can insert a sharp knife and lift the top away. Very neat.What I think happens is that with the cracker firmly in contact with the shell, releasing the handle causes a shock wave to travel down the bell causing the bell to try to ring, which it does by expanding and contracting and as it does this it slips just a tiny fraction down the shell, and then it contracting again. Inside the bell there is a small edge (like the inside edge of an opened tin can - one of those with a ring pull. and as the bell contracts this cuts into the eggshell all the way round. leaving the shell nowhere to go but up or down, i.e. to crack, which it does leaving no mess.I'm not a physicist, or engineer, so if you are and can explain that more simply and correctly the please feel free to correct me.The cracker is soundly made if stainless steel of good quality and feels quite rugged and made to last, and I enjoyed the experiment of using it on eggs boiled for five minutes, what it is like on soft boiled eggs I can't say as I only like the yolk to be runny. In this case 'caveat emptor' I think its a good tool and worth what I paid for it.

Was a little sceptical about this item will it work or just a gimmick well I can tell you it is one of the best kitchen gadgets we have purchased to date.This little thing just works you just seat it on top of your boiled egg pull and release the plunger and off comes the top of the egg shell in one brilliant

Nice product, well made, would be good as a giftWe have had mixed results using it. If the egg has cracked slightly during boiling, then the force of the cracker normally makes more damage to the sides of the egg. But if egg is solid then we have had some really good ones where it works just like it is displayed on the pack. Normally we get somewhere between these two extremes... Takes off the top but leaves a bit of debris on the sides.Still better than trying to force your way in with a blunt knife or back of a spoon though

I was pleasantly surprised to have this 'egg-capper' working. Works best on thick egg-shells.

This is quite a good gadget but it takes about three pings before the top of the eggs are easily removable and even then it is sometimes necessary to use a knife to give it a little help. Also, be careful of your fingers as, having to hold the eggs still whilst performing the task, it is easy to burn yourself - unless you have asbestos fingers, that is!

It does what it's suppose to. I'm kind of amazed at how well it works once you get used to it. Just press it firmly against the egg, pull the top part, than let it go. Try lifting it, very slowly. If there is any resistance, just give it another go and that should do the trick.On my 3rd breakfast I managed to get a clean cut on all 4 eggs and I keep getting a clean cut ever since. So it's a great product and it works amazingly well, just need to learn to use it so don't get discouraged if it doesn't work well the first couple times

Two sharp blows from this gadget produces a perfect circular crack all round the egg. It works equally well with large hen and with duck eggs and I would not now be without it. The only very minor problem I had was that if you use it when the egg is in a metal egg cup, the transferred energy can cause the bottom of the egg to crack as well! Easy answer - hold the egg in a napkin - well worth it!
