Available Features and Options

420HC Steel

This is Buck's standard blade material because it approaches the wear resistance of high carbon alloys while delivering the corrosion resistance of chromium stainless steels. Add our exclusive heat-treat process and you have a very user-friendly combination of superior corrosion resistance with excellent strength for wear resistance and durability. You also have a blade that is easy to resharpen. For best performance we harden to a Rockwell hardness of Rc 58.

Drop Point

This blade is full bellied with a strong, thick point for heavier tasks. It can also be used as a general work knife. The top of the blade drops down toward the tip, which minimizes accidental puncturing while skinning. The drop point blade is strong and very versatile.

I got this knife and was expecting it to be heavy and clumbsy but I was wrong Buck knocked this one out of the ball park. Very easy to use and feels great in the hand and this will be my new EDC I highly recommend and you want be disappointed. The only thing I would change is no lock don't need one and gets in the way but not a deal breaker love this knife.

Newest addition to EDC kit

While I wasn't immediately sold on the Inertia upon first seeing the knife in the display case, my opinion changed the moment I put it in my hand. Since purchasing my first unit, I have since picked up a second knife just to make sure I am not without. I would highly recommend this knife for a daily carry. Just be careful who you allow to check it out, as you will no doubt find people are hard pressed to give it back once they cycle it.

what I was looking for

This knife sounded real nice on the description so I had to have it. It is just what I wanted , didn't need to look anywhere else. It's a Buck so I knew I wouldn't be disappointed. Get this knife you'll love it.

The UnRushed ASAP

For EDC I've mostly carried Buck ASAP knives. Having a quick one hand deployment has been quite handy if I'm controlling a distressed horse with one hand. I prefer the 3"+ blades but those models, like the Tempest, keep disappearing. I've got a Rush but I carry a Bantam most of the time for the blade size. When I saw the Inertia I bought it. It is my favorite of the lot so far. It is not an ASAP. It has the same lock style as the Rush but the blade action is about 1/2 the speed; casual but always full extension. UnRushed. It deploys with your index finger. I have no idea why Buck says the ASAP knives open with "a flick of the thumb". It does have a cutout for thumb action but you'll never use it. When opened the lock lays flush with the handle. Very nice. It is very secure when closed and tucked away when open. This style lock has been troublesome over the years. The early models sometimes released when pulled out of a pocket and the blade opened. The Quickfire lock was more secure but it had worked by a stud on the side that released frequently when I pulled it out of my jeans. It didn't release the blade though. The Inertia lock is Rush style and pretty much perfect. Secure open and closed and going in and out of my pocket. The blade has a beautifully done "stonewashed" finish to match the handle. The 420C blades are always excellent. This one seems to me sharper than any Buck knife I've ever used. It's ridiculously sharp. The slats on the handle give it a good grip. It's comfortable in my hand. Doesn't fit me quite as well as the large Bantam and it has no gimping but those are minor points. It does have a most excellent clip and properly placed not at the front pivot like on a Bantam but at the end of the handle like a Rush. This is definitely the best assisted-opening Buck knife I've ever used. I've used pretty much all of them except the Momentum. There is one drawback... The combo of the slatted sides and the stainless pocket clip make it a little tough to pull it out of a pair of Wranglers. The slats act like gear teeth over the hem at the pocket. I've gotten the habit now of flexing the tip of the clip a bit as I pull it out. No big deal. Just something to get used to. It's a great knife.
