Retractable knife / Retractable safety knife

Retractable knife

When using traditional knife,we can only cut objects in straight line ,so it's not so convenient in some occasions .To avoid the disadvantages of traditional knife,now we design a retractable safety knife. The product has a retractable structure ,so the blade of knife can be taken in like measuring tape and can be bent in arbitrary shape,thus we cut something into the shape you want. For example, wecan cut a piece of cake in arbitrary shape from the whole cake and directly put into another plate.In a word, it is very convenient to for using when cutting things.
