Best Swiss Army knife replacement parts and accessories

Start with the small genuine parts. Victorinox's own replacement tweezers, toothpick and scissor spring are the pieces that actually go missing or snap, and they drop straight into the slot in the scales — no tools, no disassembly.

• Tweezers — the single most-lost part; pick the size that matches your knife's closed length (small for 58 mm, large for 85/91/111/130 mm).
• Toothpick — same sizing rule; buy a couple so you're not reordering.
• Scissor spring — the usual fix when scissors stop springing open.
• Replacement pen — for 58 mm models with a pen slot.
• Full parts kit — for someone rebuilding or servicing several knives, or replacing blades and openers rather than just the small bits.

Match parts to your knife's closed length before ordering; that's the one thing that trips people up.
