I'd make the changes due to commonly expressed criticisms:
Spyderco:
The Hole is Ugly = We will make our customers love them. Make the hole even bigger and mirror polish it.
Compression lock is not ambidextrous/finger-slicing (Ikuchi,Tropen,etc.) = Sell sets of liners and scales with buttons. I would charge around $15-30 for a conversion package, where you select the Spyderco model and choose "Left Side Lock Liner + Right Side Button Scale" and "Right Side Lock Liner + Left Side Button Scale". Mix and match.
Paramilitary Poor Blade/Handle Ratio = Sell shorter versions of PM2/PM3 with deleted lanyard hole section. Integrate a back-spacer that doubles as lanyard hole. See Artisan Cutlery below:
Benchmade:
Uneven Grinds = Halt production and release the new 940-0, the zero bevel chisel grind until the fanbase realizes they miss us.
Pricing = Bugout is $130 (S30V+Grivory), while the SOG Terminus is $80 (S35VN+Carbon Fiber). Freek is $200 (CPM-M4+G-10), while the Hogue RSK is $160 (CPM-20CV+G-10). I would need to discount my products at least $30 to stay competitive. If I want to maintain the image of premium to justify the price, then the products will be more refined. This includes: Perfect grinds, crowned blades, mirror polished flats, and continued impeccable customer service. Also will send screws, clips and springs - no questions asked.
The Almighty Omega = Goes extinct. The Axis on the Anthem is the new standard. Every Benchmade product will have either a "long spine back-spacer" piece, or male/female sandwich scales to provide a top mounting point for the coil spring. This negates all weaknesses Omega springs had, which will make our products infinitely fidgetable and less openings to collect gunk - since the top is covered.
Kershaw/ZT:
Alphabet Soup Steel = All knives in the $20-$70 range is either 12C27, D2, 14C28N, AEB-L or Nitro-V. No more 2CrOP39(.)(.) MoVQXY? mystery steel. ZT steels will be S35VN, Elmax or M390/20CV.
ZT Refinement: ZT wasn't made to compete with William Henry. Go back to the classics that made the brand great. Fat chunks of Elmax and titanium. Make the logo smaller and less cartoonish.
Reate & Medford: Cheaper and thinner blade stock.
GEC: Less cover variety and increased production of patterns we already know people want. Make unlimited runs of Elephant Toenails with beer-barrel scales, and Beer Scouts with mammoth ivory scales. Hire enforcers to "write strongly worded letters" to Beer & Sausage flippers. Hire our first web designer.
WE/Civivi/Sencut: Explore other locktypes other than liner and framelocks. The Helix was amazing. The company needs to be bolder and stop pushing out another almost, but not quite edgy D2/G-10 model every week.
CRKT: No more glass fibers and 8CR13MOV. All knives in the $20-$70 range is either 12C27, D2, 14C28N, AEB-L or Nitro-V with micarta or G-10. Find great OEMS (WE, Lionsteel, Millit, Reate, etc.) to produce the designs from famous designers.
Artisan Cutlery/CJRB: Change the logo. Put the recoil lock on everything.
