How much tied up in my bikes you ask Eh? If you really want to know
The DH bike would have a retail value of just shy of $10000 the way its built up the trail bike would be about $4500 new as built
and the dirt jump bike is the cheap one at about $2700
Now I will be honest I payed no where near that for any of them, simply because I work at a bike shop and bought most of the parts off of the clearout lists mid year. I think I may have only sank $5000 into all 3 bikes in actual cash over a span of 5 years. In the last 12 months I have spent zero on bikes and close to $1200 on knives and knife making supplies.
For me the upper limit on what I think I would spend on a knife with no fear of using it would be about $250 over that I start to think about loosing it

I like my knives to be in that 100-175 range, you get a quality knife you can use without the fear of loosing it. Just my 2 cents though, the expensive are worth the extra money just out of my comfort zone.
