Rated 4.3 out of 5 by 11 reviewers.
Rated 4.0 out of 5.0 by Quality, value-priced taping knife Blade holds up well after lot's of uses. Bought it with the intentions of making it disposable after 1 medium-sized project but it's still going strong. Blade starting to show a little rust for cleaning the last use but prepares/cleans up easily for next project. Handle is ok with no padding. Blade has enough flex to work well for taping purposes. Also found it useful for applying a heavy stuco finish to some drywayy for an artesian look. I've even gone as far as to use it for a touch up paint guard/shield. October 5, 2012

Rated 5.0 out of 5.0 by Simple, easy to use! Hung drywall in my twenties, hated mudding and tapping. This was a great knife, used it to make walls have a smooth finish. Told to use a 24 inch, but good luck finding one! Did it's job, felt about the same as most tape knives. Satisfied with the results, guess that is all that really matters. March 18, 2014
