In 1970 I walked into CC Lumber in Corpus Christi, Texas and lay down my dollars for my first Stanly 10-099 utility blade, just like my Dad's. The old original has seen me through 40+ years of drywall, framing and carpentry. Looks old, feels good in the hand. As long as I feed it Stanley replacement blades and clean it up from time-to-time it works (and has never drawn blood). Cannot say more for a useful tool than that.

Great tool, if I had a dollar for every time I used one, I could buy the company! Never broke one,but have lost a few.

Couldn't find this knife anywhere else. Been using this reliable tool for years. Stanley is the best boxknife.

I run the construction labs at a local technical college and the Classic 99 is my go-to utility knife. It's simple, elegant, and easy to maintain. I have students bring all kinds of utility knives into the labs, and the more complicated ones are typically broken or abandoned by the end of the first semester. However, a simple, well made, utility knife like the Classic 99 will last them through graduation and beyond.

I use this knife for everything: breaking down cardboard boxes, cutting down loose bits of drywall paper when patching a hole, even scraping gum off shoes. The blades need to be changed out fairly often and I’ve had to make the occasional last-second run to the hardware store when I need a new one, but the assembly is sturdy and will last you forever. I regularly see people with Stanley knives that are ten and twenty years old. You absolutely have to own one!

like the added feature of storing additional blades

No need to reinvent the wheel, this thing works as it should.

In thirty years my Classic 99 has NEVER let me down. It'll cut anything and changing blades is a snap. Wish all my tools were so reliable.

This knife has treated me great. No gimmicks necessary, does exactly what it’s supposed too. I expect to last a long to time!

Great knife as advertised
