I think the selection available in Toronto is abysmal. There are a few custom makers in the greater Toronto area - George Tichbourne is absolutely first rate for using knives, as an example - but purveyors or retailers of custom knives? Forget it. You're pretty much limited to the phone, the net, or waiting for the twice yearly Guild shows[you just missed the October show, the next one is in April] or driving out to Wolfgang's show in the summer. Some good makers do attend the Outdoor Show and the Sportsman's Show. As far as production knives are concerned, there is an organisation that puts on a show for that, but those shows have been a little lackluster. Retail? S & R Knives at the Woodbine Mall, or whatever it's called, has quite a good selection of production knives, but everything is too expensive. Offensively marked up. However, they're not bad folks and they will deal if you are reasonable. "Warriors" on Yonge street used to have a small but good selection of fighters and even a few customs. I bought a Carbon V Trailmaster there several years ago. I don't know what they carry now. LeBaron in Mississauga has probably the best selection of production working and hunting knives and probably also the best prices around. They have a discount card you can buy, which improves the bargain. A much smaller collection but very good prices is available from MEC which is now on King Street.
The store in the north end some members were talking about is Ontario Sporting Supples who sell mostly guns, ammo, shooting/hunting supplies and some knives. They're on Steeles or Hwy 7 near the 400. The owner really does know his knives,although I don't agree with his opinion about Elishewitz, but the store carries only production knives. they also have a 10% discount card for many items. There also was a good selection of production knives at a sporting goods store on the south side of Bloor street just east of bathurst. "King Sol", I think. The good stuff was at the back. I haven't been there in years.
There is a fellow in London, he's on the net under "Spire", who carries Mad Dog. I haven't bought from him yet, but he seems to be a good man.
That's all I can think of in the Toronto area, ]except Spire which is London]. I wish we had a better [or any] selection of customs to look at and lust after. I don't think we do.
