Stanley 2.43 in. Classic 99 Retractable Utility Knife

I had my Stanley for 60 years of hard use and it still works perfectly. I have added a couple more over the last 5-10 years and they are identical my first one, and work just as well. My thanks to Stanley for not compromising on a simple but invaluable tool, as is so often the case these days. As a note, Someone told me 60 years ago that the 99E would not hold up. I also have a fixed blade (99?) but it requires a holster, and I have only used it for cutting tarpaper for roofing and siding underpayment, usually with a hooked blade. Indispensable too but my 99E is my "go-to" utility knife. Blades are easy to get in bulk.

Does it’s job of cutting boxes and string good product

bought as a replacement and have had zero problems with it and carried in a back pocket was purchased 16 years ago. In that time, it has been used to cut all on the list of things listed and then some. Fast blade changing and the fact it can store up to 5 blades makes it very handy if need to change current blade in use.

I have owned this knife and find it to be durable and easy to change blades. Besides just cutting into boxes and using the blade as a scraper It has been helpful when doing roof shingles. Blades easily interchange and hold an edge
