I don't think you know what conjecture means. We know that Jared West is the founder of Copiousity, LLC. We know that the brand Quartermaster is registered to Copiousity, LLC. We know that there are shipping manifests showing Copiousity, LLC received at least 800kg of knives/knife components from China. We know that the original address given for Quartermaster is, was and has been a single family residence since well before they were founded. We know they have ignored repeated requests for evidence of any factory or manufacturing facility in the US.
What you know, they made a claim on their website.
Your position is, indeed, conjecture, ours is an informed hypothesis supported by the available evidence. The two are rather different.
