This is a quality USA made screwdriver. You can feel the difference the first time you use it. It is heavy duty and has a chrome plated shaft to help resist rust. This may very well be the last 5/16" screwdriver that I need to purchase. Excellent tool at a volume savings discounted price.

I needed a large screwdriver this fit the bill with the larger pentagon shaped handle works great when you have larger hands. For me the angles of the handle makes it easier to grasp and turn. A nice job was done grinding the tip square. I have used it so far for putting Fernco couplings on PVC piping and digging out large rocks in my plumbing ditches. I have been getting less fatigued using screwdriver. Great for the price. I would recommend this.

As expected, it's a nice screwdriver from Husky. Husky doesn't make the highest quality tools but Husky tools are always very durable. This screwdriver feels very good in the hand, although it's a little heavy. It has a large blade so don't expect to use this on small screws. The handle is very comfortable and gives you a good grip.I can honestly recommend this screwdriver to anyone who wants a quality screwdriver that should last a long time.I received this product in exchange for an honest review, which I have provided.

21 June 2014

I bought this Klein 600-6 screwdriver to replace an older one I snapped the shaft on while using it as an improvised pry bar to straighten a bent jack screw on an RV leveling jack. That's not something I can fault the screwdriver for though and is also not something I would normally even use a screwdriver for, but unfortunately at the time I was in a very remote location with no other option available. It actually got the job done, but sacrificed itself in the process. I prefer the older style handle with the rubber outer grip like this screwdriver has over Klein's newer style Journeyman screwdriver handles. The square shank on this driver also seems stronger than Klein's similar size round shank screwdriver and allows the uses of a wrench when a little extra ... MoreI bought this Klein 600-6 screwdriver to replace an older one I snapped the shaft on while using it as an improvised pry bar to straighten a bent jack screw on an RV leveling jack. That's not something I can fault the screwdriver for though and is also not something I would normally even use a screwdriver for, but unfortunately at the time I was in a very remote location with no other option available. It actually got the job done, but sacrificed itself in the process. I prefer the older style handle with the rubber outer grip like this screwdriver has over Klein's newer style Journeyman screwdriver handles. The square shank on this driver also seems stronger than Klein's similar size round shank screwdriver and allows the uses of a wrench when a little extra leverage or torque is needed. This 5/16" Keystone tip screwdriver looks and feels exactly like the old one and is still made in the USA, so overall I'm happy with it.

I have SK and Klein screwdrivers and both work tremendously well. I bought my son a set and he compared them to his old set that he had. He immediately noticed a quality difference. Don't skimp on tools!! Even if you don't make a living with ,them you will be very disappointed if you go cheap. Klein is a great way to go.

Love a Klein screwdriver. I have owned these for years and turned thousands of screws. Love the new handle wrap design, Klein has changed it up just a bit over the years, compared to my older ones but I like it. Very snug and no moving when using. The tip is highly resilient and retains its sharp crisp shape after thousands of screws being turned. Just a great screwdriver.

My husband and I are DIYers and we have many tools but this one is the best. It is a must have tool in your tool box. It's made of a strong material, larger than any ordinary flat screwdriver. The handle is made of a sturdy material that is firmly constructed for any tough job. It's a tool that I will recommend to any person who likes to do things at home or for any other job that requires strength. It's a very useful and helpul tool.

This 6 inch slotted screwdriver by Husky is a good quality tool. The rubberized handle grips well and allows you to get a solid purchase on the screwdriver. The blade tip is nickel and chrome plated and extremely hard.I have been replacing all my Craftsman tools with Husky products now and have been completely satisfied with their performance. Plus they all have a lifetime warranty.

This is my 2nd purchase of this item. My first was stolen. Otherwise I dont think that I would have ever needed to buy this again. There is no better American screwdriver than Klein. Still Made in the USA! For professions or homeowners who want the best. This heavy duty flat-head can be used for whatever you will throw at it. Screws, chisel, prybar, etc. The grip is ergonomic and reduces chance of electrocution. (Non-insulated but still rubber.)

5 December 2020

This size screwdriver is a must have for every tool belt. The 5/16” blade provides the required size for easily working with moderate size electrical apparatus. In addition, the square shank permits additional torque when combined with an appropriate sized wrench. And yes, this tool is tough enough to also be used for mild prying when the situation arises.
