Anyone own both of these? Which is your favorite for what and why? I have the bk9 as well as bk7 and bk10 but dont have the ontario sp10 and any comments i have made on the sp10 have been the opinions of others such as the weak point. But before adding the sp10 to my 'arsenal' i would like to know how well it stands up to the becker bk9 and if it's better in certain situations. thanks for your responses.
