## Product: OLFA SK-4 Safety Utility Knife
**Brand:** ‎OLFA

The OLFA SK-4 Safety Knife is designed to be used by both right-handed and left-handed folks. According to the manufacturer's description, you can make it left-hand-friendly by flipping the blade 180 degrees. 

This feature is handy, but from what we've gathered, there are mixed opinions on how easy it is for left-handed users. Some people have mentioned that using it with the left thumb can be a bit tricky, especially for long periods, which might mean a bit of a learning curve.

Now, about that blade retraction—the SK-4 has this neat self-retracting feature where the blade automatically goes back inside as soon as you let go of the slider. This is a big help in preventing accidents, especially when you're using it in a busy workspace where you're constantly grabbing for it.

Our research points out that the knife is built to be tough and long-lasting, which is great if you need something that can handle a lot of action. 

So, if you're in the market for a utility knife with solid safety features and a bit of flexibility for left or right hand use, this one might be a good fit. Just keep in mind, adapting to it if you're left-handed might take a little practice, but the safety pay-off could be worth the effort.
