Hiking camping gas refill adaptor
Hand made from Copper. Unit is approximately 12mm diameter by 18mm long. Enables you to refill your gas canister in a similar fashion that you would a gas cigarette lighter.
With this device you can refill the lindal screw in type gas canisters (see photos) very popular with hiking and camping, from the cheap butane cassette type canisters normally used in small portable heaters and Chinese type cooking stoves, which cost around 95p each so you can save quite a bit of money by refilling.
