Maybe its because its early in the morning, but I'm struggling to understand the original post.

Are you asking if its OK to swap out the Sebenza and start wearing a LM on your person? If so, by all means!!! ... if that meets your needs and is comfortable.

Are you asking if its OK to stop wearing the Sebenza on your person, and instead carry a LM in a bag? If so, NO!!! ... you should really be carrying the blade on your person.

Are you asking if the LM is as "good" a knife as the Sebenza? If so, that's apples and very nice oranges ... two different tools for different uses & needs. Neither one is innately better than the other if they meet your needs.
