Question: I just recieved this. Opened it once with great difficulty, now it won't close no matter what I do. Any suggestions?
Document: The build of the knife feels solid a is a good value. However, the &#34;assisted opening&#34; needs some assistance to open all the way. Also the paint was rubbed off on some areas. This is the 5th one of these knives that I bought and certainly the worse of the bunch.
Answer: no
