"At £6.99 I thought this was a very good value for money and it comes with 20 spare blades. The knife also has internal storage for some blades. You turn the brass coloured knob to lock the blade in place and loosen the knob to retract the blade and if you keep loosen the knob the knife opens up so you can change the blade and provides access to the blade storage part. The blade can also be locked in the retracted position so that is a good safety feature."
"Very hard to change blades. It falls apart when unscrewed as its a loose hinge. Nothing like my good old Dolphin knife. This is not fit for everyday use where you need to change blades frequently. Otherwise very good value and as sharp as your blades are!!!"
