Here's why and what you can do:
* "Tiger USA Knives" is not a specific brand. There are many knife manufacturers that use "Tiger" or "USA" in their branding.
* You may be thinking of a specific model or design. If you have a particular knife in mind, try searching online for its specific name or model number.
* Check online retailers: Popular online retailers like Amazon, Walmart, and BladeHQ often carry a wide variety of knives. Searching on these sites may help you find the specific knife you're looking for.
If you have more information about the knife you're looking for (like a picture, specific features, or a retailer where you saw it), please provide it, and I'll do my best to help you find the official website.
