Recalls, Issues & Notes
🔧 Known Issues
Lock Stick After Disassembly
Users report that after disassembling the ACE Grand for cleaning or maintenance, the lock can develop significant lock stick (the lockbar feels sticky or difficult to disengage when closing the blade).
Source ↗Pivot Pin Fitment — Loose Stop Pin
Some users report the pivot or stop pin holes being slightly undersized, causing the pins to feel loose or rattle over time.

Fix: Proper Reassembly Sequence
Loosen all screws. Close the blade. Push the show-side scale up and the lock-side scale down. While holding this alignment, tighten everything back up starting with the pivot screw and working toward the back. This resets proper lock face alignment. A small amount of graphite or nano-oil on the lock face can also help.
Source ↗Fix: Oversize Pin Holes
Advanced users have used a 1/8" drill bit to oversize the stock holes for a tighter pin fit. This eliminates any extra movement. Only recommended for experienced modifiers — otherwise contact GiantMouse warranty support.
