The Kenko Boston shaker in two lines
These are the two tins of the Boston shake, built with weighted bases electronically welded all the way round and 1mm thick 18/10 stainless steel: a 28oz tin, 18cm tall and 325g, and the 18oz Kenko half tin, 13cm tall and 250g.
Who it is for
For bartenders who read the numbers before the photos. The supplier declares everything on this pair, thickness included, and the numbers describe a tool built to last: a millimetre of steel is a lot for a tin, and a continuous weld on the base is what separates a professional tool from a generic catalogue one.
The base welded all the way round
The extra weight on the base can be fixed in two ways: spot welding, which is quick and cheap, or a continuous weld around the whole circumference. The second costs more and does one precise thing: with no gaps, water cannot get between base and body. In a spot-welded tin, moisture that works its way in comes out over time as drips in the next drink, and carries smells with it. The Kenko half tin and its large tin have no such gap, which is the technical reason a pair like this costs more than an ordinary one.

One millimetre, and why you feel it
Many tins are under 0.8mm. At that thickness the rim deforms the first time it hits the bar top, and once it loses its roundness the pair starts leaking during the shake: the drink runs down the wrist and onto the floor. At one millimetre the tin keeps its shape for years. The trade-off is weight, which is declared here: 325g for the large tin and 250g for the small one, nearly 600g empty and around 1.5kg full. It is a pair for a trained wrist.
The heights tell you how it sits in the hand
18cm for the large tin and 13cm for the half tin: closed, the pair measures just over 20cm and sits comfortably in one hand. It is the classic Boston proportion, and because the supplier declares it you can tell before buying whether it suits your hand, which on a tool used fifty times a night matters.
Washing by finish
Silver is bare 18/10 stainless steel with no plating and can go in the dishwasher. Black, gold, copper and bronze are plated and dishwasher cycles dull them in patches: mild soap by hand, rinse and dry straight away. Whatever the finish, pay attention to the weighted base, where water lingers longest. A tool built to last ten years is worth thirty seconds of proper washing.
