Of course it should stay. Forums are the best way to spread knowledge, discuss both criticisms and complaints, and troubleshoot/find necessary resources, etc. Like every other maker, I am sure time is something people have very little of, but additional presence on a forum would still be a plus. From the perspective as a consumer, when a maker keeps a presence on an area in which two-way interaction can occur to address needs, concerns, positive/negative feedback, and open up R&D to customer input, everyone wins. Benefits to the maker are happier customers, greater sales, more repeat customers, and a very good source of user-feedback that can be used for continuous quality improvement. While it is impossible to please everyone every single time, this presence still makes a big difference in many instances.
Like many other makers on this forum, Emerson has contributed significantly to the modern stage we are in as far as edged tools and edged weapons go. It is a brand that people looking for a quality folder should certain consider when weighing the options available. That becomes harder without Emerson's presence here.
Additionally, the knowledge base created by Emerson on edged weapons training is also notable and extensive. A forum can help discuss training materials and help owners best utilize an edged weapon to survive in a SHTF situation.
