STANLEY 10-099 Classic 99 6'' Retractable Utility Knife with 3 Heavy-Duty Blades (Steel Grey)

The first hands on impression was just amazing. When you hold it in your hands you know how sturdy heavy it is built and it can withstand anything. It's a heavy (weight) and that's a good thing you don't need to press too hard to cut anything. The blades are super strong and the snap-off blades are no match for it. Sharpness wise it is very sharp but not extraordinary razor sharp as it is meant for heavy duty work. This is my first trapezoidal utility knife so I can't compare the blades with any other brand but these blades are thick and super strong. I tested cutting MDF and popsicle sticks and it cuts 10 times better than any offline market snap-off knives. Overall i got it at 315 and at this price it is worth every penny. You get 2 extra blades in the compartment. One of the best purchases I've made. There is no competition. (Except maybe Taparia UK-3?)

Material is very good.Easy to use & assembleGrip & size is the best

It is simple, cheap, functional, reliable and durable.I have been using it for more than 3 years now. I bought it from a shop in Delhi for ₹260. Initially I faced difficulty in getting the spare blades. But now the blades are available with most of the Stanley dealers.It is a well made heavy duty knife with die cast zinc body which can really withstand heavy impacts. With one blade the knife weighs 155g. It is 6 inches long. The blade (11-921) can be extended in five different positions up to a maximum of 1 inch.If I remember correctly, the knife came with three 11-921H heavy duty blades. These blades are really sharp and they retain the sharpness for a long time. However, they do have a tendency to rust, especially if you leave them in the storage area inside the handle.To replace the blades you need to open the handle by removing the screw at the side of the handle. The screw can be removed using a coin and you don't need a screwdriver for it.There is a small compartment inside the handle to store the spare blades. It can hold up to five spare blades. But I prefer not to keep any blades in it. The blades in the compartment are not held firmly and rattles a lot while working with the knife. The blades will also start getting rusted if you leave them in the compartment. If you really need to have spare blades then keep only one blade wrapped in plastic. First dip the blade in machine oil then wrap it in plastic.I mainly use it for marking wood for cutting, cutting vinyl etc. It is ideal for scoring the cut line before cutting to prevent splintering. It can also be used for stripping thick insulation. I have used it with the hook blade to cut plexiglass.This is a heavy duty knife and may not be suitable for light and delicate work. For smaller work, knives like the Stanley 10-418 or the Stanley 10-425 are more suitable.Update on 14-Sep-17: I bought another one from Amazon for ₹199. This time I got a made in India knife.

Update. - Going strong for almost a year. Happy that I switched to this product from the plastic body cutters. Blades have a good life too.Key points about this Utility Knife-1. Heavy duty solid moulded metal body and good set of three blades.2. The body is very well designed and upper and lower half stay together with interlocking of the two parts and a good size screw.3. The product says Made in India and blades are marked made in England so I assume main body is made in India and assembly done here locally.4. Overall finish is good.5. If you are used to plastic body blades you will find this cutter very heavy. Feels solid in hand6. Overall length of cutter is around 6 inch.7. The blade is not auto retract. You need to push down the retracting mechanism knob to move the blade out and inside of the body.8. The blade length coming out of the body is adjustable with 3 settings.9. Two sides of blade are usable so each blade can be reused by changing the blade install orientation to the second edge when first edge gets blunt. Blades are very well built and should last long.10. The weight of blade helps you to cut things with less effort. If you do a lot of shopping online the blade works well for opening packages and carton boxes. This is my primary knife now for opening packages and boxes at home and at work .Tip - All blades come stored inside the body so its not shipped ready-to-use. Have a screwdriver handy to open the unit and install blade before first use. Blades move around in storage area so i wrapped them in a paper before putting the screw back to close the unit.Caution - As expected with sharp tools be cautious in using this cutter. Being heavy if it falls on your feet etc it can do a lot of damage. Use with care. Also posting few pictures.Will I buy it again - Definitely.
