Bridlington Filecutter

[Catswhiskers]

My g.g. Uncle Frank has confused me completely. Large as life in Bridlington on the 1851, time served as a filecutter and living in lodgings in Sheffield on the 1861  and here's the thing,  filecutting in Bridlington in 1871. 

Now I know about filecutting, if he was cutting somebody was forging them in the first place. Has anybody seen a file forger in Bridlington? Was anybody else filecutting in Bridlington?  Was he bringing them in from somewhere else?

Filecutting in Bridlington sounds rather like having a fishing boat in Sheffield.

Either way he'd packed it in to be barman by 1881 but I'm mighty curious about it.
