W: Now, could you tell me where the idea for the business first came from?
M: Well, the original shop was opened by a retired printer by the name of Gruby. Mr. Gruby, being left-handed himself, thought of the idea to trying promote a few products for lefthanders.
W: And how did he then go about actually setting up the business?
M: Well, he looked for any left-handed products that might already be on the market, which were very few, and then contacted the manufacturers with the idea of having products produced for him, mainly in the scissor range to start with.
W: Right. So you do commission some part of your stock.
M: Yes, very much so. About 75 percent of our stock is specially made for us.
W: And the rest of it?
M: Hmm, the rest of it now, some 25, 30 years after Mr. Gruby’s initial efforts, there are more left-handed products actually on the market. Manufacturers are now beginning to see that there is a market for left-handed products.
W: And what’s the range of your stock?
M: The range consists of a variety of scissors, from children scissors to scissors for tailors, hairdressers, etc. We also have a large range of kitchenware.
W: What’s the competition like? Do you have quite a lot of competition?
M: There are other people in the business now as specialists, but only as mail order outlets. But we have a shop here in central London plus a mail order outlet. And we are without any doubt the largest supplier of left-handed items.
