HI Karl,

Thanks for the question.

The only place i can find at present are Glaxo ( link below)

https://glaxio.co.uk/amtech-foldback-utility-knife-stainless-steel-s0280/

Alternatively if you send me an email to  Contact@dktools.com with your postcode i will tell you your local stockist and if they dont have them in stock they could order them for you.

Hope this helps
