Where Can I Sell Knives Online? The Complete Guide

The Best Platforms for Selling Knives Online

Whether you're clearing out a collection, flipping knives for profit, or selling custom work, the platform you choose dramatically affects prices, buyer quality, and transaction safety. The knife secondary market has grown enormously — certain limited editions now appreciate 200-500% above retail. This growth has brought more sellers, more platforms, and more competition.

1. Reddit (r/knife_swap)

Best for: Mid-range and premium knife sales to knowledgeable buyers

The r/knife_swap subreddit is the most knife-community-native selling platform:

• Buyers are educated enthusiasts who understand market value
• A feedback/reputation system ("swapluck") tracks seller reliability
• No platform fees (though PayPal fees apply)
• Strict posting rules ensure quality listings
• Fastest sales for popular brands

To succeed, build reputation through positive transactions. New accounts with no feedback will struggle to sell high-value knives.

2. eBay

Best for: Vintage knives, discontinued models, and reaching mainstream buyers

• Largest buyer audience of any platform
• Good for rare, vintage pieces
• Auction format can drive prices up on desirable pieces
• 10–13% platform fees plus PayPal fees
• Buyer protection can favor fraudulent buyers — photograph everything

On a $200 knife, expect to pay roughly $25-30 in combined fees.

3. Facebook Marketplace and Groups

Best for: Local sales, lower-value knives

• Dedicated knife selling groups
• Local meetups eliminate shipping complications
• No platform fees for direct transactions
• Only accept PayPal Goods & Services or cash in person

4. BladeForums.net (Buy/Sell/Trade)

Best for: Premium and custom knives, reaching serious collectors

• Oldest and most respected knife forum community
• Premium marketplace for high-end knives
• Reputation system dating back decades
• Best for knives $100+ where buyer knowledge matters

5. Etsy

Best for: Custom, handmade, and artisan knives

• Strong market for custom blade work, handle scales, sheaths
• 6.5% transaction fee plus listing fees
• Buyers expect unique, handcrafted items — not ideal for reselling production knives

6. Mercari

Best for: Quick sales at slight discount

• Simple listing, good mobile experience
• 10% selling fee
• Less knife-savvy buyers

7. Specialized Knife Retailers

• BladeHQ: Consignment and trade-in options
• KnifeCenter: Will consider buying quality used knives
• DLT Trading: Offers trade-in credit

Shipping Knives Legally

• USPS prohibits shipping switchblades across state lines (federal law: 15 USC § 1241)
• UPS and FedEx can ship knives including automatics
• Always pack knives safely — edge protected, secure packaging
• Declare accurately — never obscure what you're shipping

Shipping Best Practices

• Wrap each knife individually in bubble wrap or paper
• Secure the blade so it can't open during transit
• Use a rigid box, not a padded envelope
• Include tracking and insurance for valuable knives
• Photograph before shipping as evidence of condition

Pricing Your Knives

• Like new / unused: 75–85% of retail
• Light use, no marks: 60–75% of retail
• Used with minor marks: 45–60% of retail
• Heavy use or modifications: 30–45% of retail
• Mint/unopened: 90-100% of retail

Factors That Increase Value

• Discontinued models, limited editions, steel upgrades, custom work, cultural significance

Avoiding Scams

• Never ship before receiving payment
• Beware of overpayment/refund scams
• Use platforms with buyer and seller protection
• Document everything
