The size of your blade is something that you need to consider when deciding which pocket knife is best for you. A smaller knife is better for EDC (every day carry) as they are obviously easier to fit in your pocket, and a lot less threatening.
If you brought out a huge 10” knife at work in front of your colleagues, just to cut your laces or something, then there would probably be a bit of a commotion.
The length of the best survival pocket knife should be between 6 and 12”, and you should choose the blade length according to what you’re most likely going to be using it for. If it cuts wood, shaves bark from branches, and can help to prepare you a dinner in the wilderness, you have the right knife.
The type of metal used for the blade can vary.
High carbon steel tends to be significantly tougher than stainless steel, as the grain structure is much denser. They may be a little bit more prone to corrosion, and a bit less wear-resistant than those of stainless steel.
With stainless steel, they’re significantly less prone to corrosion, due to the inclusion of around 12.5% Chromium. Blades made of this material may also be harder to sharpen as opposed to high carbon steel.
You should consider the Rockwell Hardness of the blade before you make a sharp decision. Bladesmiths use a scale called the Rockwell Scale C to determine the hardness of knife blades.
A super tough blade will have a Rockwell Hardness of around 58-62 HRC.
A Rockwell Hardness of 54-57 is a good compromise between edge holding ability and toughness.
The harder a blade is, the more likely it is to break. A hard knife will certainly hold an edge, though.
In the past, a surveillance security system typically consisted of several cameras connected—either hardwired or wireless— to a digital video recorder (DVR), which recorded the images and displayed them on a closed circuit television (CCTV) or monitor. Nowadays, it’s much easier to have a standalone security camera. Whether you have one camera or several, they work with your home’s internet network to send footage right to your computer or mobile device. Most consumer cameras store data internally, on a removable microSD card, or remotely on the cloud.
The camera’s viewing angle determines how much space the camera will cover. Wide-angle lenses reduce the number of cameras required to monitor your home. Some outdoor security cameras have a wide-angle lens that may show a 360-degree view, but the best security cameras have a view of at least 100 degrees or better.
There are two outdoor security camera designs – dome or bullet-shaped. The dome-shaped outdoor security camera is known to be less obvious to unwelcome visitors because they offer a 360 swivel that makes it difficult to determine their direction. On the other hand, bullet-shaped cameras are more common. They have a cylinder shape that clearly stands out to alert thieves that your home is under surveillance.
If you want to playback your home’s outdoor activity, you’ll need a camera with onboard video storage or cloud recording capabilities. Most cameras with recording capabilities have a built-in secure digital (SD) or microSD slot that allows for sufficient recording space. Once the memory card is full, you’ll need to delete footage or store it elsewhere. Some popular cameras automatically override expired videos, which may not be most ideal if you need to keep a video. On the contrary, some security camera providers offer cloud storage monthly plans to securely store videos on the cloud. You can easily access them anytime, anywhere by signing into your account on your mobile device or using a mobile app.
