This Stanley Folding Knife has been designed with user comfort and safety in mind. The auto-retract feature means you don't have to worry about accidentally leaving the blade engaged, possibly damaging yourself, someone else or property. In order to keep the blade extended, the user must keep their finger on the blade slider. Once you remove your finger the blade will safely retract. The slim-line folding lock-back design means this knife is ideal for keeping in the van, in your toolbox or in your pocket. The highly visible red finish makes sure the knife isn't easy to lose sight of and the blade can be changed without the need for additional tools. In order to replace the blade, simply rotate the cover on the blade slider and remove the blade. The blade slider is also magnetic so it quickly and easily attracts the new blade and holds it in place.   ~~PLEASE NOTE - You must be 18 years of age or older to purchase this product.
