The WTF in this case actually stands for Wrench That Fits ($30), so yes, this little combination keychain/multi-tool can be safely given to dad on Father’s Day without fear of him washing your mouth out with Irish Spring. Besides the legit wrench that tackles jobs in a multitude of sizes, the WTF also has a small ruler on each side and a built-in pry bar. And just think: If dad enjoys getting a gift called WTF, maybe you’ll be able to sprinkle in a more FUs around the holidays!
