Technical Information

Lee Valley Tools has acquired Hock Tools. The transition is under way as we ship them inventory and they work to get a new Hock Tools website up and running and processing orders. If an item here is "Out of Stock", it may be in stock at Lee Valley, and is definitely on order and being produced at the factory!

Please contact with the Hock item number, and they’ll be glad to advise if they have it, or when they expect it. Note that pricing will remain the same, and shipping will be at no charge.
