If you want a versatile solution that will last a long time, get a Norton Tri Stone (oil) - https://www.amazon.com/Norton-Professional-Multi-Oilstone-Knife-Sharpening/dp/B06Y6HRJQ4/

I learned on this when I worked the line (a few decades ago) and I have this exact system at home. The well, the large surface area and three grits are great. I can sharpen many knives at a time, quickly and consistently. And bonus, the stones can be flipped when worn for continued use. I test the sharpness by shaving the hair off my forearm - they are sharp.

If you get Whustof knives, be aware of the thick bolster of the knife where it meets/extends to the heel of the blade - this can make using a sharpening stone a bit more tedious since you'll have to hold the knife to avoid dragging that part across the stone.

I use Victorinox as basic knives to do most of the basic cutting at home - I also used these on the line (when the brand was originally called Forschener). I also have forged Japanese knives and use water whetstones, but do not recommend them for your Whustof/Global knives.
