With a few exceptions, there are buyers ready and waiting.

Especially, if the blade you want to buy/sell has been out of production for a bit.
The Exchange forum is heavily moderated... for a reason. It can get out of control quickly with "chattiness" and such.
If you want to put in a "I want to buy" then Exchange>Wanted To Buy>Knives is the appropriate place to post.
If you want to trade, then Exchange>Trade>Knives and Tools is best.
If you want to sell (first buy a Gold Membership) and post a Busse/Swamp/Scrap in the Exchange>For Sale Production Knives (Individual)>Busse / Swamprat / Scrapyard Knives For Sale sub-forum.
A note on memberships: Anyone can buy or trade their blades on the Exchange. Only a Gold Member or above can sell. Any offers to Buy/Sell/Trade *must* take place in the exchange or back channel. Discussion of Buy/Sale/Trade offers are unwelcome in other forums.
Not to sound heavy handed but if you list a blade for Trade, don't buy a Gold or above, and it is discovered you *sold* it through this solicitation one would receive an infraction - potentially enough points to be banned.
Welcome!!
