I use this on my SAK explorer a five layer SAK but can be used on the thicker models as well. 

You will receive 2 versions of the clip as corkscrew locations can be different between models. I will send your clips by standard letter so no tracking will be given ,so your postage cost is low and included in the price. Depending on sales I may do other colors in the future. (Tool not included) only the clips

Thankyou
