The first thing that comes to mind is a special knife holder. The choice of such coasters with a whole collection of knives is very large today, you can find really design options that will accurately decorate the work area in the kitchen.
If you have imagination and time, you can make a stand for knives yourself. From wood, for example. Coasters made of bamboo sticks look very unusual, by the way, they are very convenient. Some even use spaghetti or beautifully layered colored beans, peas and other grains..
The knife holder can be integrated into the open shelf. Convenient, everything is near, but at the same time does not clutter up the work surface.
Storage system in a special box. This is a very popular option, because besides knives, there are a lot of cutlery in the kitchen. It is important to choose a system with containers of different sizes, for each cutlery. However, now there are a lot of such ready-made options, for any kitchen there is one.
Special stand on the railing. Such hanging structures are used very widely in kitchens, allowing you to keep the most important items in sight in the cooking area. For knives, you will have to provide a special holder.
Magnets. Very convenient and compact. After all, the knife is made of metal, so it will be reliably magnetised; you do not need to get into the corresponding hole in the stand and pull it out. And it is very easy and simple to care for the magnetic stripe. Alternatively, such a magnetic storage system can be built into a narrow box sliding out from above. This will help hide sharp objects from children..
Store knives directly in the worktop? Why not. It can be a simple narrow strip where the blades are inserted, several holes of different sizes in a wooden tabletop. And even a special drawer sliding into the countertop, which will hide the main kitchen “weapon” from prying eyes.
