Facebook Buy-Sell-Trade groups

The invite-only Facebook groups where high-end knife owners post asks, offers, and trade proposals directly to their peers.

FB-BST is shorthand for the invite-only Facebook buy-sell-trade groups where high-end knife owners post asks, offers, and trade proposals directly to their peers. Shirogorov listings appear on FB-BST at higher volume than on any other secondary-market venue tracked by NIIVES.

What FB-BST is

Facebook hosts hundreds of BST groups for knife collectors. A small subset trade at the high-end tier where Shirogorov, Chris Reeve, Grimsmo, RJ Martin, and Sebenza-adjacent makers change hands. Membership rules vary by group: some are open, most require an application with references, and a few require a sponsor already in the group.

The groups are not marketplaces in the platform sense. Facebook provides the forum and the group’s mechanics; the transactions happen between members, off-platform for payment. That distinction matters because Facebook does not offer buyer protection, escrow, or transaction records for a BST sale. The group’s own norms and its members’ feedback histories are the trust infrastructure.

How Shirogorov trades happen on FB-BST

An FB-BST listing typically opens with a title line naming the model and configuration, an asking figure or a request for offers, a set of photos, and a condition summary against the community’s shared vocabulary for used-knife grading. Sellers usually include shots of the pivot area, the lock face, the certificate of authenticity, and the box. The best-run groups require a timestamp shot with the seller’s group handle to prove the knife is in hand.

Trade proposals often accompany asks. A common pattern is a Shirogorov offered against a specific list of other Shirogorovs the seller wants, sometimes with cash on one side to balance value. Straight sales at fixed prices are the other common pattern; offer-based sales sit between the two.

Volume is high enough that a typical week in an active FB-BST group carries several Shirogorov listings across production, sprint run, and Custom Division tiers. Full customs are rarer and often move without a public post through relationships built inside the group.

Fraud patterns and clone activity

FB-BST attracts scam attempts because Facebook’s account infrastructure is weak. Cloned accounts, hijacked profiles, and dropshipped counterfeits all appear. The community defends with layered signals: post history requirements, feedback reference threads, insistence on Google Voice or invoiced payments rather than Friends and Family transfers on Venmo or PayPal, and quick moderation removals when a listing pattern-matches a known scam template. Even so, a small number of successful frauds move through each year, usually against newer members who skip the vetting steps.

The clones circulating on FB-BST are mostly F95T and F3 knockoffs and occasionally NeOn-family fakes. A listing that shows an F95T with a serial that does not match the seller’s box photo, or a listing where the photos are recycled from an earlier public sale, are the most common tells.

How to participate

  • Apply to one of the recognized Shirogorov-heavy groups. Existing members can point at which are active. Applications usually require a set of screenshots of feedback history from other groups or forums.
  • Post an introduction thread once accepted. Building a small feedback record on lower-value transactions before listing a high-value knife is the community norm.
  • List in the group’s format. Deviating from the title convention, the photo requirements, or the payment norms attracts moderator attention.
  • Use payment methods that carry buyer or seller protection. Wire, cryptocurrency, and Friends and Family transfers are red flags on both sides.
  • Escalate to the moderators before public accusations. The best-run groups resolve disputes privately when possible.

What NIIVES observes on FB-BST

NIIVES tracks Shirogorov listings and transactions across the Shirogorov-heavy FB-BST groups it holds membership in. Coverage includes ask prices, sale prices where the group culture surfaces them (often as a “sold” edit or a follow-up thank-you post), model and configuration, and condition disclosures.

FB-BST is the highest-volume contributor to the NIIVES aggregate by observation count. The data quality is good on ask prices and configuration; sale prices are more uneven because not every sold post updates with the final figure. NIIVES weighs FB-BST heavily in the aggregate for line-level model activity and less heavily for precise transaction values.
