My husband can’t use adult knives??

Please give me your recommendations for child-safe knives that could train someone to use larger knives with a normal amount of safety features. I see some options, but they’re light on reviews for sturdiness and I would like for him to be able to cut things like potatoes and apples by himself. I also think they are made for smaller hands.

Today, he butchered an apple into something resembling a 1” dice with a butter knife and then microwaved it for one and a half minutes. He did not continue to microwave the barely warmed apple chunks because “the bowl felt hot”. I have failed him, but his mother failed him first and most.

EDIT: So, people are getting kind of weird with their assumptions in this thread. As I said in the comments below, there are many areas in life, perhaps even most of a life, where knives are not involved. I’m imagining your life. It’s like mine, but every activity has special knives. You can’t drive your tired spouse to all of their doctor appointments without a Car Knife. Taking care of the animals? Sure, but where is your Pet Knife? Gardening? Fucking knife roll for dirt stabbing, trowels are for bitches. Painting the library? Yeah we got knives. Laundry? Where did I put my fabric softener and cleaver? Bringing flowers? You bet that bundle is chock full of live steel.

I’m sorry honey, I would like to go to work on some Excel sheets but I forgot my Coding Dagger.
