I am in the UK and always see over sees cakers using these extra long serated knives to level their cakes and would like to get one for myself but cannot seem to find on in the UK

I use a long serrated bread knife.

i've got a long bread knife but i want an extra long one

If www.bakedecco.com ships overseas I got mine from them. The blade not including the handle is 14 inches. I paid $17.60 USD for it.

There is a 19" length blade here: http://www.surbitonart.co.uk/acatalog/Knives.html

I'm sorry I can't tell you exactly where, but the extra long super sharp knife I have (and serrated) is one my husband originally bought (and I immediately stole for myself) for fishing! As in for fishing, cleaning, gutting (sorry). And it was approximately $20! So check around by you at a fishing / sporting goods type of place. As long as its new, it doesn't have to be specifically for baking. Mine has got to be 16-18" long and has a plastic sheath for storage. Its also thin and flexible so it's great to torte a oversize item. Good luck - you never know where you will find something you need!

thank you very much for all the replies, i now have a 19" blade one ordered
