Grip and Comfort

Using the wrench for extended periods means grip comfort is important. I checked if the handles had textured or ergonomic surfaces to prevent slipping and reduce hand fatigue. This makes a noticeable difference in my overall experience.

Price and Value

Finally, I balanced price against features and durability. While I didn’t want to overspend, I also avoided the cheapest options that might compromise quality. Finding a set that offers good value ensures I get dependable tools without breaking the bank.
