Or even replace the handle if it breaks. I intend this should last as long as some of the 150+ yo stuff I see advertised on ebay for $200 and up. A brand new antique, stronger than anything I've seen go by on ebay so far since I've not seen any with buttress threads. IOW still working long after I'm gone. Which could be most any time now since I'm now coming up on my 88th, but the battery in my pacemaker still has around 5 years to go... The TAVR valve in place of the aortic in my heart is a question mark though. Take care and stay well, Bill.
