Tsubota Pearl Lighters
Handmade by a small Japanese family business who have been making lighters for three generations. They use the highest quality Japanese steel.
Each lighter has a built in tamper and pick/scraper. I bought one at the Chicago Pipe Show 2011 and found it is very bit a good as my Corona and less expensive & far better than the Colibri that broke all the time (made in China) and after 3 replacement lighters I gave up. Each Tsubota Pearl lighter is guaranteed for 1 year.
The lighters use a flint for spark and butane for fuel. What is interesting is there is a two way flame adjustment. The maximum you set at it and then the normal screw adjustment as fuel volume changes. This first adjustment prevents it flaring up after filling. A first class lighter for a reasonable price. I found that mine lasts about ten days between fillings and I use it all the time.
I find they have a soft flame that doesn't char the rim of smooth pipes.
Dimensions = 2 5/8" x 1 3/8" wide, Weight Filled = 2.5 oz's.
