I own the 4 Blue Spork To Go set. Pros Lightweight. Has a knife built-in…
Has a knife built-in on one side of the fork.
Includes a zippered case to keep them clean & organized.
Safe to use with non-stick cookware.
Will not rust.
More sturdy than the common disposable plastic-ware but far thinner and weaker than I expected. Claims to be heat resistant but not so much. Mine bent while stirring a very hot cup of coffee.
The knife is not very useful. The little serrated teeth tend to crumble into your food when trying to cut with it. Plus, you often need an additional utensil anyway to hold the food while cutting, especially with hot food. If I'm camping, I already have a pocketknife at minimum.
The zippered case is not very sturdy or durable.
Not a proper spork in my opinion. I much prefer to have both the spoon and fork on the same end as I find them easier to use. Not only are they easier to use, imagine wanting to switch to using the fork after using the spoon or vise versa. Your hand gets to hold the end covered with food. Also, when camping, your hands are probably not real sanitary so switching back and forth...dirty hands now covered in food, back and forth.
Overpriced for the quality.
Tapirus also sells a Spork of Steel Classic set of 4 for just 2 or 3 dollars more. It is a proper spork with the spoon and fork on the same end and a normal end to hold on to. It doesn't have the integrated knife. It's much stronger than this thin plastic spork. The only downside to me is that you can damage non-stick cookware with it if not very careful.
