Weight matching</div> <div>parts leaves more of the integrity of the hammer intact - hammer felt mass. </div> <div><br></div> <div>I take weight from the area which used to have a cove. I see no benefit</div> <div>to the cove.  What is it anyway, a leftover from a time when hammers needed</div> <div>to be pared down to the max, compensating for high action ratio?  Left in for</div> <div>tradition?  A cove removes so little weight it is hardly worth the effort especially</div> <div>today with better action geometry applications.</div> <div><br> Regards,<br> <br> Jon Page</div> </body> </html>
