We weren’t able to find it as an active Channellock product, so as Eschoendorff suggests, it’s probably available only as “new old stock.” Still, it’s pretty interesting.
As of this moment, Froogle picked up one on eBay for $25. But if you’re interested in owning one, you’re probably best off checking around at your favorite boutique tool shop that might still have one sitting around. Let us know if you find one!
