Disappointing, but not unexpected. These look to be very similar to the equivalent Boll series blades (or, in the case of the ALC, similar to the Viscaria, or Boll Spirit as well). No doubt there will be minor differences, but I can't see anything which justifies the higher price. Teessport aren't known for keen pricing, but they have the TBS at £89.99, the Boll ALC at £115.99, and the Jike ALC at £143.99. I can't see the sense in that.
And that's without looking around the world for better pricing. tt-japan have the Boll ALC at approx £70, and the Jike ALC at approx £88. Of course, Butterfly's restrictive policy on shipping means you have to find inventive ways of actually ordering internationally...
